DESCRIPTION

You can query/set/replace/unset options with this command. The name is actually the section and the key separated by a dot, and the value will be escaped.

Multiple lines can be added to an option by using the --add option. If you want to update or unset an option which can occur on multiple lines, a POSIX regexp value_regex needs to be given. Only the existing values that match the regexp are updated or unset. If you want to handle the lines that do not match the regex, just prepend a single exclamation mark in front (see also the section called “EXAMPLES”).

The type specifier can be either --int or --bool, to make git config ensure that the variable(s) are of the given type and convert the value to the canonical form (simple decimal number for int, a "true" or "false" string for bool), or --path, which does some path expansion (see --path below). If no type specifier is passed, no checks or transformations are performed on the value.

The file-option can be one of --system, --global or --file which specify where the values will be read from or written to. The default is to assume the config file of the current repository, .git/config unless defined otherwise with GIT_DIR and GIT_CONFIG (see the section called “FILES”).

This command will fail if:

    1. The config file is invalid,

    2. Can not write to the config file,

    3. no section was provided,

    4. the section or key is invalid,

    5. you try to unset an option which does not exist,

    6. you try to unset/set an option for which multiple lines match, or

    7. you use --global option without $HOME being properly set.

OPTIONS

--replace-all
    Default behavior is to replace at most one line. This replaces all lines matching the key (and optionally the value_regex).

--add
    Adds a new line to the option without altering any existing values. This is the same as providing ^$ as the value_regex in --replace-all.

--get
    Get the value for a given key (optionally filtered by a regex matching the value). Returns error code 1 if the key was not found and error code 2 if multiple key values were found.

--get-all
    Like get, but does not fail if the number of values for the key is not exactly one.

--get-regexp
    Like --get-all, but interprets the name as a regular expression. Also outputs the key names.

--global
    For writing options: write to global ~/.gitconfig file rather than the repository .git/config.

    For reading options: read only from global ~/.gitconfig rather than from all available files.

    See also the section called “FILES”.

--system
    For writing options: write to system-wide $(prefix)/etc/gitconfig rather than the repository .git/config.

    For reading options: read only from system-wide $(prefix)/etc/gitconfig rather than from all available files.

    See also the section called “FILES”.

-f config-file, --file config-file
    Use the given config file instead of the one specified by GIT_CONFIG.

--remove-section
    Remove the given section from the configuration file.

--rename-section
    Rename the given section to a new name.

--unset
    Remove the line matching the key from config file.

--unset-all
    Remove all lines matching the key from config file.

-l, --list
    List all variables set in config file.

--bool
    git config will ensure that the output is "true" or "false"

--int
    git config will ensure that the output is a simple decimal number. An optional value suffix of k, m, or g in the config file will cause the value to be multiplied by 1024, 1048576, or 1073741824 prior to output.

--bool-or-int
    git config will ensure that the output matches the format of either --bool or --int, as described above.

--path
    git-config will expand leading ~ to the value of $HOME, and ~user to the home directory for the specified user. This option has no effect when setting the value (but you can use git config bla ~/ from the command line to let your shell do the expansion).

-z, --null
    For all options that output values and/or keys, always end values with the null character (instead of a newline). Use newline instead as a delimiter between key and value. This allows for secure parsing of the output without getting confused e.g. by values that contain line breaks.

--get-colorbool name [stdout-is-tty]
    Find the color setting for name (e.g. color.diff) and output "true" or "false". stdout-is-tty should be either "true" or "false", and is taken into account when configuration says "auto". If stdout-is-tty is missing, then checks the standard output of the command itself, and exits with status 0 if color is to be used, or exits with status 1 otherwise. When the color setting for name is undefined, the command uses color.ui as fallback.

--get-color name [default]
    Find the color configured for name (e.g. color.diff.new) and output it as the ANSI color escape sequence to the standard output. The optional default parameter is used instead, if there is no color configured for name.

-e, --edit
    Opens an editor to modify the specified config file; either --system, --global, or repository (default).

FILES

If not set explicitly with --file, there are three files where git config will search for configuration options:

$GIT_DIR/config
    Repository specific configuration file. (The filename is of course relative to the repository root, not the working directory.)

~/.gitconfig
    User-specific configuration file. Also called "global" configuration file.

$(prefix)/etc/gitconfig
    System-wide configuration file.

If no further options are given, all reading options will read all of these files that are available. If the global or the system-wide configuration file are not available they will be ignored. If the repository configuration file is not available or readable, git config will exit with a non-zero error code. However, in neither case will an error message be issued.

All writing options will per default write to the repository specific configuration file. Note that this also affects options like --replace-all and --unset. git config will only ever change one file at a time.

You can override these rules either by command line options or by environment variables. The --global and the --system options will limit the file used to the global or system-wide file respectively. The GIT_CONFIG environment variable has a similar effect, but you can specify any filename you want.

ENVIRONMENT

GIT_CONFIG
    Take the configuration from the given file instead of .git/config. Using the "--global" option forces this to ~/.gitconfig. Using the "--system" option forces this to $(prefix)/etc/gitconfig.

See also the section called “FILES”.

EXAMPLES

Given a .git/config like this:

    #
    # This is the config file, and
    # a '#' or ';' character indicates
    # a comment
    #

    ; core variables
    [core]
            ; Don't trust file modes
            filemode = false

    ; Our diff algorithm
    [diff]
            external = /usr/local/bin/diff-wrapper
            renames = true

    ; Proxy settings
    [core]
            gitproxy="proxy-command" for kernel.org
            gitproxy=default-proxy ; for all the rest

you can set the filemode to true with

    % git config core.filemode true

The hypothetical proxy command entries actually have a postfix to discern what URL they apply to. Here is how to change the entry for kernel.org to "ssh".

    % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'

This makes sure that only the key/value pair for kernel.org is replaced.

To delete the entry for renames, do

    % git config --unset diff.renames

If you want to delete an entry for a multivar (like core.gitproxy above), you have to provide a regex matching the value of exactly one line.

To query the value for a given key, do

    % git config --get core.filemode

or

    % git config core.filemode

or, to query a multivar:

    % git config --get core.gitproxy "for kernel.org$"

If you want to know all the values for a multivar, do:

    % git config --get-all core.gitproxy

If you like to live dangerously, you can replace all core.gitproxy by a new one with

    % git config --replace-all core.gitproxy ssh

However, if you really only want to replace the line for the default proxy, i.e. the one without a "for ..." postfix, do something like this:

    % git config core.gitproxy ssh '! for '

To actually match only values with an exclamation mark, you have to

    % git config section.key value '[!]'

To add a new proxy, without altering any of the existing ones, use

    % git config core.gitproxy '"proxy-command" for example.com'

An example to use customized color from the configuration in your script:

    #!/bin/sh
    WS=$(git config --get-color color.diff.whitespace "blue reverse")
    RESET=$(git config --get-color "" "reset")
    echo "${WS}your whitespace color or blue reverse${RESET}"

CONFIGURATION FILE

The git configuration file contains a number of variables that affect the git command's behavior. The .git/config file in each repository is used to store the configuration for that repository, and $HOME/.gitconfig is used to store a per-user configuration as fallback values for the .git/config file. The file /etc/gitconfig can be used to store a system-wide default configuration.

The configuration variables are used by both the git plumbing and the porcelains. The variables are divided into sections, wherein the fully qualified variable name of the variable itself is the last dot-separated segment and the section name is everything before the last dot. The variable names are case-insensitive and only alphanumeric characters are allowed. Some variables may appear multiple times.

  Syntax

The syntax is fairly flexible and permissive; whitespaces are mostly ignored. The # and ; characters begin comments to the end of line, blank lines are ignored.

The file consists of sections and variables. A section begins with the name of the section in square brackets and continues until the next section begins. Section names are not case sensitive. Only alphanumeric characters, - and . are allowed in section names. Each variable must belong to some section, which means that there must be a section header before the first setting of a variable.

Sections can be further divided into subsections. To begin a subsection put its name in double quotes, separated by space from the section name, in the section header, like in the example below:

            [section "subsection"]

Subsection names are case sensitive and can contain any characters except newline (doublequote " and backslash have to be escaped as \" and \\, respectively). Section headers cannot span multiple lines. Variables may belong directly to a section or to a given subsection. You can have [section] if you have [section "subsection"], but you don't need to.

There is also a case insensitive alternative [section.subsection] syntax. In this syntax, subsection names follow the same restrictions as for section names.

All the other lines (and the remainder of the line after the section header) are recognized as setting variables, in the form name = value. If there is no equal sign on the line, the entire line is taken as name and the variable is recognized as boolean "true". The variable names are case-insensitive and only alphanumeric characters and - are allowed. There can be more than one value for a given variable; we say then that variable is multivalued.

Leading and trailing whitespace in a variable value is discarded. Internal whitespace within a variable value is retained verbatim.

The values following the equals sign in variable assign are all either a string, an integer, or a boolean. Boolean values may be given as yes/no, 0/1, true/false or on/off. Case is not significant in boolean values, when converting value to the canonical form using --bool type specifier; git config will ensure that the output is "true" or "false".

String values may be entirely or partially enclosed in double quotes. You need to enclose variable values in double quotes if you want to preserve leading or trailing whitespace, or if the variable value contains comment characters (i.e. it contains # or ;). Double quote " and backslash \ characters in variable values must be escaped: use \" for " and \\ for \.

The following escape sequences (beside \" and \\) are recognized: \n for newline character (NL), \t for horizontal tabulation (HT, TAB) and \b for backspace (BS). No other char escape sequence, nor octal char sequences are valid.

Variable values ending in a \ are continued on the next line in the customary UNIX fashion.

Some variables may require a special value format.

  Example

    # Core variables
    [core]
            ; Don't trust file modes
            filemode = false

    # Our diff algorithm
    [diff]
            external = /usr/local/bin/diff-wrapper
            renames = true

    [branch "devel"]
            remote = origin
            merge = refs/heads/devel

    # Proxy settings
    [core]
            gitProxy="ssh" for "kernel.org"
            gitProxy=default-proxy ; for the rest

  Variables

Note that this list is non-comprehensive and not necessarily complete. For command-specific variables, you will find a more detailed description in the appropriate manual page. You will find a description of non-core porcelain configuration variables in the respective porcelain documentation.

advice.*
    When set to true, display the given optional help message. When set to false, do not display. The configuration variables are:

    pushNonFastForward
        Advice shown when git-push(1) refuses non-fast-forward refs. Default: true.

    statusHints
        Directions on how to stage/unstage/add shown in the output of git-status(1) and the template shown when writing commit messages. Default: true.

    commitBeforeMerge
        Advice shown when git-merge(1) refuses to merge to avoid overwritting local changes. Default: true.

    resolveConflict
        Advices shown by various commands when conflicts prevent the operation from being performed. Default: true.

    implicitIdentity
        Advice on how to set your identity configuration when your information is guessed from the system username and domain name. Default: true.

    detachedHead
        Advice shown when you used :git-checkout(1) to move to the detach HEAD state, to instruct how to create a local branch after the fact. Default: true.

core.fileMode
    If false, the executable bit differences between the index and the working copy are ignored; useful on broken filesystems like FAT. See git-update-index(1).

    The default is true, except git-clone(1) or git-init(1) will probe and set core.fileMode false if appropriate when the repository is created.

core.ignoreCygwinFSTricks
    This option is only used by Cygwin implementation of Git. If false, the Cygwin stat() and lstat() functions are used. This may be useful if your repository consists of a few separate directories joined in one hierarchy using Cygwin mount. If true, Git uses native Win32 API whenever it is possible and falls back to Cygwin functions only to handle symbol links. The native mode is more than twice faster than normal Cygwin l/stat() functions. True by default, unless core.filemode is true, in which case ignoreCygwinFSTricks is ignored as Cygwin's POSIX emulation is required to support core.filemode.

core.ignorecase
    If true, this option enables various workarounds to enable git to work better on filesystems that are not case sensitive, like FAT. For example, if a directory listing finds "makefile" when git expects "Makefile", git will assume it is really the same file, and continue to remember it as "Makefile".

    The default is false, except git-clone(1) or git-init(1) will probe and set core.ignorecase true if appropriate when the repository is created.

core.trustctime
    If false, the ctime differences between the index and the working copy are ignored; useful when the inode change time is regularly modified by something outside Git (file system crawlers and some backup systems). See git-update-index(1). True by default.

core.quotepath
    The commands that output paths (e.g. ls-files, diff), when not given the -z option, will quote "unusual" characters in the pathname by enclosing the pathname in a double-quote pair and with backslashes the same way strings in C source code are quoted. If this variable is set to false, the bytes higher than 0x80 are not quoted but output as verbatim. Note that double quote, backslash and control characters are always quoted without -z regardless of the setting of this variable.

core.autocrlf
    If true, makes git convert CRLF at the end of lines in text files to LF when reading from the work tree, and convert in reverse when writing to the work tree. The variable can be set to input, in which case the conversion happens only while reading from the work tree but files are written out to the work tree with LF at the end of lines. A file is considered "text" (i.e. be subjected to the autocrlf mechanism) based on the file's crlf attribute, or if crlf is unspecified, based on the file's contents. See gitattributes(5).

core.safecrlf
    If true, makes git check if converting CRLF as controlled by core.autocrlf is reversible. Git will verify if a command modifies a file in the work tree either directly or indirectly. For example, committing a file followed by checking out the same file should yield the original file in the work tree. If this is not the case for the current setting of core.autocrlf, git will reject the file. The variable can be set to "warn", in which case git will only warn about an irreversible conversion but continue the operation.

    CRLF conversion bears a slight chance of corrupting data. autocrlf=true will convert CRLF to LF during commit and LF to CRLF during checkout. A file that contains a mixture of LF and CRLF before the commit cannot be recreated by git. For text files this is the right thing to do: it corrects line endings such that we have only LF line endings in the repository. But for binary files that are accidentally classified as text the conversion can corrupt data.

    If you recognize such corruption early you can easily fix it by setting the conversion type explicitly in .gitattributes. Right after committing you still have the original file in your work tree and this file is not yet corrupted. You can explicitly tell git that this file is binary and git will handle the file appropriately.

    Unfortunately, the desired effect of cleaning up text files with mixed line endings and the undesired effect of corrupting binary files cannot be distinguished. In both cases CRLFs are removed in an irreversible way. For text files this is the right thing to do because CRLFs are line endings, while for binary files converting CRLFs corrupts data.

    Note, this safety check does not mean that a checkout will generate a file identical to the original file for a different setting of core.autocrlf, but only for the current one. For example, a text file with LF would be accepted with core.autocrlf=input and could later be checked out with core.autocrlf=true, in which case the resulting file would contain CRLF, although the original file contained LF. However, in both work trees the line endings would be consistent, that is either all LF or all CRLF, but never mixed. A file with mixed line endings would be reported by the core.safecrlf mechanism.

core.symlinks
    If false, symbolic links are checked out as small plain files that contain the link text. git-update-index(1) and git-add(1) will not change the recorded type to regular file. Useful on filesystems like FAT that do not support symbolic links.

    The default is true, except git-clone(1) or git-init(1) will probe and set core.symlinks false if appropriate when the repository is created.

core.gitProxy
    A "proxy command" to execute (as command host port) instead of establishing direct connection to the remote server when using the git protocol for fetching. If the variable value is in the "COMMAND for DOMAIN" format, the command is applied only on hostnames ending with the specified domain string. This variable may be set multiple times and is matched in the given order; the first match wins.

    Can be overridden by the GIT_PROXY_COMMAND environment variable (which always applies universally, without the special "for" handling).

    The special string none can be used as the proxy command to specify that no proxy be used for a given domain pattern. This is useful for excluding servers inside a firewall from proxy use, while defaulting to a common proxy for external domains.

core.ignoreStat
    If true, commands which modify both the working tree and the index will mark the updated paths with the "assume unchanged" bit in the index. These marked files are then assumed to stay unchanged in the working copy, until you mark them otherwise manually - Git will not detect the file changes by lstat() calls. This is useful on systems where those are very slow, such as Microsoft Windows. See git-update-index(1). False by default.

core.preferSymlinkRefs
    Instead of the default "symref" format for HEAD and other symbolic reference files, use symbolic links. This is sometimes needed to work with old scripts that expect HEAD to be a symbolic link.

core.bare
    If true this repository is assumed to be bare and has no working directory associated with it. If this is the case a number of commands that require a working directory will be disabled, such as git-add(1) or git-merge(1).

    This setting is automatically guessed by git-clone(1) or git-init(1) when the repository was created. By default a repository that ends in "/.git" is assumed to be not bare (bare = false), while all other repositories are assumed to be bare (bare = true).

core.worktree
    Set the path to the root of the work tree. This can be overridden by the GIT_WORK_TREE environment variable and the --work-tree command line option. It can be an absolute path or a relative path to the .git directory, either specified by --git-dir or GIT_DIR, or automatically discovered. If --git-dir or GIT_DIR are specified but none of --work-tree, GIT_WORK_TREE and core.worktree is specified, the current working directory is regarded as the root of the work tree.

    Note that this variable is honored even when set in a configuration file in a ".git" subdirectory of a directory, and its value differs from the latter directory (e.g. "/path/to/.git/config" has core.worktree set to "/different/path"), which is most likely a misconfiguration. Running git commands in "/path/to" directory will still use "/different/path" as the root of the work tree and can cause great confusion to the users.

core.logAllRefUpdates
    Enable the reflog. Updates to a ref <ref> is logged to the file "$GIT_DIR/logs/<ref>", by appending the new and old SHA1, the date/time and the reason of the update, but only when the file exists. If this configuration variable is set to true, missing "$GIT_DIR/logs/<ref>" file is automatically created for branch heads.

    This information can be used to determine what commit was the tip of a branch "2 days ago".

    This value is true by default in a repository that has a working directory associated with it, and false by default in a bare repository.

core.repositoryFormatVersion
    Internal variable identifying the repository format and layout version.

core.sharedRepository
    When group (or true), the repository is made shareable between several users in a group (making sure all the files and objects are group-writable). When all (or world or everybody), the repository will be readable by all users, additionally to being group-shareable. When umask (or false), git will use permissions reported by umask(2). When 0xxx, where 0xxx is an octal number, files in the repository will have this mode value. 0xxx will override user's umask value (whereas the other options will only override requested parts of the user's umask value). Examples: 0660 will make the repo read/write-able for the owner and group, but inaccessible to others (equivalent to group unless umask is e.g. 0022). 0640 is a repository that is group-readable but not group-writable. See git-init(1). False by default.

core.warnAmbiguousRefs
    If true, git will warn you if the ref name you passed it is ambiguous and might match multiple refs in the .git/refs/ tree. True by default.

core.compression
    An integer -1..9, indicating a default compression level. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If set, this provides a default to other compression variables, such as core.loosecompression and pack.compression.

core.loosecompression
    An integer -1..9, indicating the compression level for objects that are not in a pack file. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If not set, defaults to core.compression. If that is not set, defaults to 1 (best speed).

core.packedGitWindowSize
    Number of bytes of a pack file to map into memory in a single mapping operation. Larger window sizes may allow your system to process a smaller number of large pack files more quickly. Smaller window sizes will negatively affect performance due to increased calls to the operating system's memory manager, but may improve performance when accessing a large number of large pack files.

    Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32 MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should be reasonable for all users/operating systems. You probably do not need to adjust this value.

    Common unit suffixes of k, m, or g are supported.

core.packedGitLimit
    Maximum number of bytes to map simultaneously into memory from pack files. If Git needs to access more than this many bytes at once to complete an operation it will unmap existing regions to reclaim virtual address space within the process.

    Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms. This should be reasonable for all users/operating systems, except on the largest projects. You probably do not need to adjust this value.

    Common unit suffixes of k, m, or g are supported.

core.deltaBaseCacheLimit
    Maximum number of bytes to reserve for caching base objects that multiple deltafied objects reference. By storing the entire decompressed base objects in a cache Git is able to avoid unpacking and decompressing frequently used base objects multiple times.

    Default is 16 MiB on all platforms. This should be reasonable for all users/operating systems, except on the largest projects. You probably do not need to adjust this value.

    Common unit suffixes of k, m, or g are supported.

core.bigFileThreshold
    Files larger than this size are stored deflated, without attempting delta compression. Storing large files without delta compression avoids excessive memory usage, at the slight expense of increased disk usage.

    Default is 512 MiB on all platforms. This should be reasonable for most projects as source code and other text files can still be delta compressed, but larger binary media files won't be.

    Common unit suffixes of k, m, or g are supported.

    Currently only git-fast-import(1) honors this setting.

core.excludesfile
    In addition to .gitignore (per-directory) and .git/info/exclude, git looks into this file for patterns of files which are not meant to be tracked. "~/" is expanded to the value of $HOME and "~user/" to the specified user's home directory. See gitignore(5).

core.editor
    Commands such as commit and tag that lets you edit messages by launching an editor uses the value of this variable when it is set, and the environment variable GIT_EDITOR is not set. See git-var(1).

core.pager
    The command that git will use to paginate output. Can be overridden with the GIT_PAGER environment variable. Note that git sets the LESS environment variable to FRSX if it is unset when it runs the pager. One can change these settings by setting the LESS variable to some other value. Alternately, these settings can be overridden on a project or global basis by setting the core.pager option. Setting core.pager has no affect on the LESS environment variable behaviour above, so if you want to override git's default settings this way, you need to be explicit. For example, to disable the S option in a backward compatible manner, set core.pager to less -+$LESS -FRX. This will be passed to the shell by git, which will translate the final command to LESS=FRSX less -+FRSX -FRX.

core.whitespace
    A comma separated list of common whitespace problems to notice. git diff will use color.diff.whitespace to highlight them, and git apply --whitespace=error will consider them as errors. You can prefix - to disable any of them (e.g. -trailing-space):

        • blank-at-eol treats trailing whitespaces at the end of the line as an error (enabled by default).

        • space-before-tab treats a space character that appears immediately before a tab character in the initial indent part of the line as an error (enabled by default).

        • indent-with-non-tab treats a line that is indented with 8 or more space characters as an error (not enabled by default).

        • blank-at-eof treats blank lines added at the end of file as an error (enabled by default).

        • trailing-space is a short-hand to cover both blank-at-eol and blank-at-eof.

        • cr-at-eol treats a carriage-return at the end of line as part of the line terminator, i.e. with it, trailing-space does not trigger if the character before such a carriage-return is not a whitespace (not enabled by default).

core.fsyncobjectfiles
    This boolean will enable fsync() when writing object files.

    This is a total waste of time and effort on a filesystem that orders data writes properly, but can be useful for filesystems that do not use journalling (traditional UNIX filesystems) or that only journal metadata and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").

core.preloadindex
    Enable parallel index preload for operations like git diff

    This can speed up operations like git diff and git status especially on filesystems like NFS that have weak caching semantics and thus relatively high IO latencies. With this set to true, git will do the index comparison to the filesystem data in parallel, allowing overlapping IO's.

core.createObject
    You can set this to link, in which case a hardlink followed by a delete of the source are used to make sure that object creation will not overwrite existing objects.

    On some file system/operating system combinations, this is unreliable. Set this config setting to rename there; However, This will remove the check that makes sure that existing object files will not get overwritten.

core.notesRef
    When showing commit messages, also show notes which are stored in the given ref. The ref must be fully qualified. If the given ref does not exist, it is not an error but means that no notes should be printed.

    This setting defaults to "refs/notes/commits", and it can be overridden by the GIT_NOTES_REF environment variable. See git-notes(1).

core.sparseCheckout
    Enable "sparse checkout" feature. See section "Sparse checkout" in git-read-tree(1) for more information.

add.ignore-errors
    Tells git add to continue adding files when some files cannot be added due to indexing errors. Equivalent to the --ignore-errors option of git-add(1).

alias.*
    Command aliases for the git(1) command wrapper - e.g. after defining "alias.last = cat-file commit HEAD", the invocation "git last" is equivalent to "git cat-file commit HEAD". To avoid confusion and troubles with script usage, aliases that hide existing git commands are ignored. Arguments are split by spaces, the usual shell quoting and escaping is supported. quote pair and a backslash can be used to quote them.

    If the alias expansion is prefixed with an exclamation point, it will be treated as a shell command. For example, defining "alias.new = !gitk --all --not ORIG_HEAD", the invocation "git new" is equivalent to running the shell command "gitk --all --not ORIG_HEAD". Note that shell commands will be executed from the top-level directory of a repository, which may not necessarily be the current directory.

am.keepcr
    If true, git-am will call git-mailsplit for patches in mbox format with parameter --keep-cr. In this case git-mailsplit will not remove \r from lines ending with \r\n. Can be overrriden by giving --no-keep-cr from the command line. See git-am(1), git-mailsplit(1).

apply.ignorewhitespace
    When set to change, tells git apply to ignore changes in whitespace, in the same way as the --ignore-space-change option. When set to one of: no, none, never, false tells git apply to respect all whitespace differences. See git-apply(1).

apply.whitespace
    Tells git apply how to handle whitespaces, in the same way as the --whitespace option. See git-apply(1).

branch.autosetupmerge
    Tells git branch and git checkout to set up new branches so that git-pull(1) will appropriately merge from the starting point branch. Note that even if this option is not set, this behavior can be chosen per-branch using the --track and --no-track options. The valid settings are: false — no automatic setup is done; true — automatic setup is done when the starting point is a remote branch; always — automatic setup is done when the starting point is either a local branch or remote branch. This option defaults to true.

branch.autosetuprebase
    When a new branch is created with git branch or git checkout that tracks another branch, this variable tells git to set up pull to rebase instead of merge (see "branch.<name>.rebase"). When never, rebase is never automatically set to true. When local, rebase is set to true for tracked branches of other local branches. When remote, rebase is set to true for tracked branches of remote branches. When always, rebase will be set to true for all tracking branches. See "branch.autosetupmerge" for details on how to set up a branch to track another branch. This option defaults to never.

branch.<name>.remote
    When in branch <name>, it tells git fetch and git push which remote to fetch from/push to. It defaults to origin if no remote is configured. origin is also used if you are not on any branch.

branch.<name>.merge
    Defines, together with branch.<name>.remote, the upstream branch for the given branch. It tells git fetch/git pull which branch to merge and can also affect git push (see push.default). When in branch <name>, it tells git fetch the default refspec to be marked for merging in FETCH_HEAD. The value is handled like the remote part of a refspec, and must match a ref which is fetched from the remote given by "branch.<name>.remote". The merge information is used by git pull (which at first calls git fetch) to lookup the default branch for merging. Without this option, git pull defaults to merge the first refspec fetched. Specify multiple values to get an octopus merge. If you wish to setup git pull so that it merges into <name> from another branch in the local repository, you can point branch.<name>.merge to the desired branch, and use the special setting . (a period) for branch.<name>.remote.

branch.<name>.mergeoptions
    Sets default options for merging into branch <name>. The syntax and supported options are the same as those of git-merge(1), but option values containing whitespace characters are currently not supported.

branch.<name>.rebase
    When true, rebase the branch <name> on top of the fetched branch, instead of merging the default branch from the default remote when "git pull" is run. NOTE: this is a possibly dangerous operation; do not use it unless you understand the implications (see git-rebase(1) for details).

browser.<tool>.cmd
    Specify the command to invoke the specified browser. The specified command is evaluated in shell with the URLs passed as arguments. (See git-web--browse(1).)

browser.<tool>.path
    Override the path for the given tool that may be used to browse HTML help (see -w option in git-help(1)) or a working repository in gitweb (see git-instaweb(1)).

clean.requireForce
    A boolean to make git-clean do nothing unless given -f or -n. Defaults to true.

color.branch
    A boolean to enable/disable color in the output of git-branch(1). May be set to always, false (or never) or auto (or true), in which case colors are used only when the output is to a terminal. Defaults to false.

color.branch.<slot>
    Use customized color for branch coloration. <slot> is one of current (the current branch), local (a local branch), remote (a tracking branch in refs/remotes/), plain (other refs).

    The value for these configuration variables is a list of colors (at most two) and attributes (at most one), separated by spaces. The colors accepted are normal, black, red, green, yellow, blue, magenta, cyan and white; the attributes are bold, dim, ul, blink and reverse. The first color given is the foreground; the second is the background. The position of the attribute, if any, doesn't matter.

color.diff
    When set to always, always use colors in patch. When false (or never), never. When set to true or auto, use colors only when the output is to the terminal. Defaults to false.

color.diff.<slot>
    Use customized color for diff colorization. <slot> specifies which part of the patch to use the specified color, and is one of plain (context text), meta (metainformation), frag (hunk header), func (function in hunk header), old (removed lines), new (added lines), commit (commit headers), or whitespace (highlighting whitespace errors). The values of these variables may be specified as in color.branch.<slot>.

color.grep
    When set to always, always highlight matches. When false (or never), never. When set to true or auto, use color only when the output is written to the terminal. Defaults to false.

color.grep.<slot>
    Use customized color for grep colorization. <slot> specifies which part of the line to use the specified color, and is one of

    context
        non-matching text in context lines (when using -A, -B, or -C)

    filename
        filename prefix (when not using -h)

    function
        function name lines (when using -p)

    linenumber
        line number prefix (when using -n)

    match
        matching text

    selected
        non-matching text in selected lines

    separator
        separators between fields on a line (:, -, and =) and between hunks (--)

    The values of these variables may be specified as in color.branch.<slot>.

color.interactive
    When set to always, always use colors for interactive prompts and displays (such as those used by "git-add --interactive"). When false (or never), never. When set to true or auto, use colors only when the output is to the terminal. Defaults to false.

color.interactive.<slot>
    Use customized color for git add --interactive output. <slot> may be prompt, header, help or error, for four distinct types of normal output from interactive commands. The values of these variables may be specified as in color.branch.<slot>.

color.pager
    A boolean to enable/disable colored output when the pager is in use (default is true).

color.showbranch
    A boolean to enable/disable color in the output of git-show-branch(1). May be set to always, false (or never) or auto (or true), in which case colors are used only when the output is to a terminal. Defaults to false.

color.status
    A boolean to enable/disable color in the output of git-status(1). May be set to always, false (or never) or auto (or true), in which case colors are used only when the output is to a terminal. Defaults to false.

color.status.<slot>
    Use customized color for status colorization. <slot> is one of header (the header text of the status message), added or updated (files which are added but not committed), changed (files which are changed but not added in the index), untracked (files which are not tracked by git), or nobranch (the color the no branch warning is shown in, defaulting to red). The values of these variables may be specified as in color.branch.<slot>.

color.ui
    When set to always, always use colors in all git commands which are capable of colored output. When false (or never), never. When set to true or auto, use colors only when the output is to the terminal. When more specific variables of color.* are set, they always take precedence over this setting. Defaults to false.

commit.status
    A boolean to enable/disable inclusion of status information in the commit message template when using an editor to prepare the commit message. Defaults to true.

commit.template
    Specify a file to use as the template for new commit messages. "~/" is expanded to the value of $HOME and "~user/" to the specified user's home directory.

diff.autorefreshindex
    When using git diff to compare with work tree files, do not consider stat-only change as changed. Instead, silently run git update-index --refresh to update the cached stat information for paths whose contents in the work tree match the contents in the index. This option defaults to true. Note that this affects only git diff Porcelain, and not lower level diff commands such as git diff-files.

diff.external
    If this config variable is set, diff generation is not performed using the internal diff machinery, but using the given command. Can be overridden with the `GIT_EXTERNAL_DIFF' environment variable. The command is called with parameters as described under "git Diffs" in git(1). Note: if you want to use an external diff program only on a subset of your files, you might want to use gitattributes(5) instead.

diff.mnemonicprefix
    If set, git diff uses a prefix pair that is different from the standard "a/" and "b/" depending on what is being compared. When this configuration is in effect, reverse diff output also swaps the order of the prefixes:

    git diff
        compares the (i)ndex and the (w)ork tree;

    git diff HEAD
        compares a (c)ommit and the (w)ork tree;

    git diff --cached
        compares a (c)ommit and the (i)ndex;

    git diff HEAD:file1 file2
        compares an (o)bject and a (w)ork tree entity;

    git diff --no-index a b
        compares two non-git things (1) and (2).

diff.renameLimit
    The number of files to consider when performing the copy/rename detection; equivalent to the git diff option -l.

diff.renames
    Tells git to detect renames. If set to any boolean value, it will enable basic rename detection. If set to "copies" or "copy", it will detect copies, as well.

diff.suppressBlankEmpty
    A boolean to inhibit the standard behavior of printing a space before each empty output line. Defaults to false.

diff.tool
    Controls which diff tool is used. diff.tool overrides merge.tool when used by git-difftool(1) and has the same valid values as merge.tool minus "tortoisemerge" and plus "kompare".

difftool.<tool>.path
    Override the path for the given tool. This is useful in case your tool is not in the PATH.

difftool.<tool>.cmd
    Specify the command to invoke the specified diff tool. The specified command is evaluated in shell with the following variables available: LOCAL is set to the name of the temporary file containing the contents of the diff pre-image and REMOTE is set to the name of the temporary file containing the contents of the diff post-image.

difftool.prompt
    Prompt before each invocation of the diff tool.

diff.wordRegex
    A POSIX Extended Regular Expression used to determine what is a "word" when performing word-by-word difference calculations. Character sequences that match the regular expression are "words", all other characters are ignorable whitespace.

fetch.unpackLimit
    If the number of objects fetched over the git native transfer is below this limit, then the objects will be unpacked into loose object files. However if the number of received objects equals or exceeds this limit then the received pack will be stored as a pack, after adding any missing delta bases. Storing the pack from a push can make the push operation complete faster, especially on slow filesystems. If not set, the value of transfer.unpackLimit is used instead.

format.attach
    Enable multipart/mixed attachments as the default for format-patch. The value can also be a double quoted string which will enable attachments as the default and set the value as the boundary. See the --attach option in git-format-patch(1).

format.numbered
    A boolean which can enable or disable sequence numbers in patch subjects. It defaults to "auto" which enables it only if there is more than one patch. It can be enabled or disabled for all messages by setting it to "true" or "false". See --numbered option in git-format-patch(1).

format.headers
    Additional email headers to include in a patch to be submitted by mail. See git-format-patch(1).

format.cc
    Additional "Cc:" headers to include in a patch to be submitted by mail. See the --cc option in git-format-patch(1).

format.subjectprefix
    The default for format-patch is to output files with the [PATCH] subject prefix. Use this variable to change that prefix.

format.suffix
    The default for format-patch is to output files with the suffix .patch. Use this variable to change that suffix (make sure to include the dot if you want it).

format.pretty
    The default pretty format for log/show/whatchanged command, See git-log(1), git-show(1), git-whatchanged(1).

format.thread
    The default threading style for git format-patch. Can be a boolean value, or shallow or deep. shallow threading makes every mail a reply to the head of the series, where the head is chosen from the cover letter, the --in-reply-to, and the first patch mail, in this order. deep threading makes every mail a reply to the previous one. A true boolean value is the same as shallow, and a false value disables threading.

format.signoff
    A boolean value which lets you enable the -s/--signoff option of format-patch by default. Note: Adding the Signed-off-by: line to a patch should be a conscious act and means that you certify you have the rights to submit this work under the same open source license. Please see the SubmittingPatches document for further discussion.

gc.aggressiveWindow
    The window size parameter used in the delta compression algorithm used by git gc --aggressive. This defaults to 250.

gc.auto
    When there are approximately more than this many loose objects in the repository, git gc --auto will pack them. Some Porcelain commands use this command to perform a light-weight garbage collection from time to time. The default value is 6700. Setting this to 0 disables it.

gc.autopacklimit
    When there are more than this many packs that are not marked with *.keep file in the repository, git gc --auto consolidates them into one larger pack. The default value is 50. Setting this to 0 disables it.

gc.packrefs
    Running git pack-refs in a repository renders it unclonable by Git versions prior to 1.5.1.2 over dumb transports such as HTTP. This variable determines whether git gc runs git pack-refs. This can be set to nobare to enable it within all non-bare repos or it can be set to a boolean value. The default is true.

gc.pruneexpire
    When git gc is run, it will call prune --expire 2.weeks.ago. Override the grace period with this config variable. The value "now" may be used to disable this grace period and always prune unreachable objects immediately.

gc.reflogexpire
    git reflog expire removes reflog entries older than this time; defaults to 90 days.

gc.reflogexpireunreachable
    git reflog expire removes reflog entries older than this time and are not reachable from the current tip; defaults to 30 days.

gc.rerereresolved
    Records of conflicted merge you resolved earlier are kept for this many days when git rerere gc is run. The default is 60 days. See git-rerere(1).

gc.rerereunresolved
    Records of conflicted merge you have not resolved are kept for this many days when git rerere gc is run. The default is 15 days. See git-rerere(1).

gitcvs.commitmsgannotation
    Append this string to each commit message. Set to empty string to disable this feature. Defaults to "via git-CVS emulator".

gitcvs.enabled
    Whether the CVS server interface is enabled for this repository. See git-cvsserver(1).

gitcvs.logfile
    Path to a log file where the CVS server interface well... logs various stuff. See git-cvsserver(1).

gitcvs.usecrlfattr
    If true, the server will look up the crlf attribute for files to determine the -k modes to use. If crlf is set, the -k mode will be left blank, so cvs clients will treat it as text. If crlf is explicitly unset, the file will be set with -kb mode, which suppresses any newline munging the client might otherwise do. If crlf is not specified, then gitcvs.allbinary is used. See gitattributes(5).

gitcvs.allbinary
    This is used if gitcvs.usecrlfattr does not resolve the correct -kb mode to use. If true, all unresolved files are sent to the client in mode -kb. This causes the client to treat them as binary files, which suppresses any newline munging it otherwise might do. Alternatively, if it is set to "guess", then the contents of the file are examined to decide if it is binary, similar to core.autocrlf.

gitcvs.dbname
    Database used by git-cvsserver to cache revision information derived from the git repository. The exact meaning depends on the used database driver, for SQLite (which is the default driver) this is a filename. Supports variable substitution (see git-cvsserver(1) for details). May not contain semicolons (;). Default: %Ggitcvs.%m.sqlite

gitcvs.dbdriver
    Used Perl DBI driver. You can specify any available driver for this here, but it might not work. git-cvsserver is tested with DBD::SQLite, reported to work with DBD::Pg, and reported not to work with DBD::mysql. Experimental feature. May not contain double colons (:). Default: SQLite. See git-cvsserver(1).

gitcvs.dbuser, gitcvs.dbpass
    Database user and password. Only useful if setting gitcvs.dbdriver, since SQLite has no concept of database users and/or passwords. gitcvs.dbuser supports variable substitution (see git-cvsserver(1) for details).

gitcvs.dbTableNamePrefix
    Database table name prefix. Prepended to the names of any database tables used, allowing a single database to be used for several repositories. Supports variable substitution (see git-cvsserver(1) for details). Any non-alphabetic characters will be replaced with underscores.

All gitcvs variables except for gitcvs.usecrlfattr and gitcvs.allbinary can also be specified as gitcvs.<access_method>.<varname> (where access_method is one of "ext" and "pserver") to make them apply only for the given access method.

gui.commitmsgwidth
    Defines how wide the commit message window is in the git-gui(1). "75" is the default.

gui.diffcontext
    Specifies how many context lines should be used in calls to diff made by the git-gui(1). The default is "5".

gui.encoding
    Specifies the default encoding to use for displaying of file contents in git-gui(1) and gitk(1). It can be overridden by setting the encoding attribute for relevant files (see gitattributes(5)). If this option is not set, the tools default to the locale encoding.

gui.matchtrackingbranch
    Determines if new branches created with git-gui(1) should default to tracking remote branches with matching names or not. Default: "false".

gui.newbranchtemplate
    Is used as suggested name when creating new branches using the git-gui(1).

gui.pruneduringfetch
    "true" if git-gui(1) should prune tracking branches when performing a fetch. The default value is "false".

gui.trustmtime
    Determines if git-gui(1) should trust the file modification timestamp or not. By default the timestamps are not trusted.

gui.spellingdictionary
    Specifies the dictionary used for spell checking commit messages in the git-gui(1). When set to "none" spell checking is turned off.

gui.fastcopyblame
    If true, git gui blame uses -C instead of -C -C for original location detection. It makes blame significantly faster on huge repositories at the expense of less thorough copy detection.

gui.copyblamethreshold
    Specifies the threshold to use in git gui blame original location detection, measured in alphanumeric characters. See the git-blame(1) manual for more information on copy detection.

gui.blamehistoryctx
    Specifies the radius of history context in days to show in gitk(1) for the selected commit, when the Show History Context menu item is invoked from git gui blame. If this variable is set to zero, the whole history is shown.

guitool.<name>.cmd
    Specifies the shell command line to execute when the corresponding item of the git-gui(1) Tools menu is invoked. This option is mandatory for every tool. The command is executed from the root of the working directory, and in the environment it receives the name of the tool as GIT_GUITOOL, the name of the currently selected file as FILENAME, and the name of the current branch as CUR_BRANCH (if the head is detached, CUR_BRANCH is empty).

guitool.<name>.needsfile
    Run the tool only if a diff is selected in the GUI. It guarantees that FILENAME is not empty.

guitool.<name>.noconsole
    Run the command silently, without creating a window to display its output.

guitool.<name>.norescan
    Don't rescan the working directory for changes after the tool finishes execution.

guitool.<name>.confirm
    Show a confirmation dialog before actually running the tool.

guitool.<name>.argprompt
    Request a string argument from the user, and pass it to the tool through the ARGS environment variable. Since requesting an argument implies confirmation, the confirm option has no effect if this is enabled. If the option is set to true, yes, or 1, the dialog uses a built-in generic prompt; otherwise the exact value of the variable is used.

guitool.<name>.revprompt
    Request a single valid revision from the user, and set the REVISION environment variable. In other aspects this option is similar to argprompt, and can be used together with it.

guitool.<name>.revunmerged
    Show only unmerged branches in the revprompt subdialog. This is useful for tools similar to merge or rebase, but not for things like checkout or reset.

guitool.<name>.title
    Specifies the title to use for the prompt dialog. The default is the tool name.

guitool.<name>.prompt
    Specifies the general prompt string to display at the top of the dialog, before subsections for argprompt and revprompt. The default value includes the actual command.

help.browser
    Specify the browser that will be used to display help in the web format. See git-help(1).

help.format
    Override the default help format used by git-help(1). Values man, info, web and html are supported. man is the default. web and html are the same.

help.autocorrect
    Automatically correct and execute mistyped commands after waiting for the given number of deciseconds (0.1 sec). If more than one command can be deduced from the entered text, nothing will be executed. If the value of this option is negative, the corrected command will be executed immediately. If the value is 0 - the command will be just shown but not executed. This is the default.

http.proxy
    Override the HTTP proxy, normally configured using the http_proxy environment variable (see curl(1)). This can be overridden on a per-remote basis; see remote.<name>.proxy

http.sslVerify
    Whether to verify the SSL certificate when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_NO_VERIFY environment variable.

http.sslCert
    File containing the SSL certificate when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CERT environment variable.

http.sslKey
    File containing the SSL private key when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_KEY environment variable.

http.sslCertPasswordProtected
    Enable git's password prompt for the SSL certificate. Otherwise OpenSSL will prompt the user, possibly many times, if the certificate or private key is encrypted. Can be overridden by the GIT_SSL_CERT_PASSWORD_PROTECTED environment variable.

http.sslCAInfo
    File containing the certificates to verify the peer with when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CAINFO environment variable.

http.sslCAPath
    Path containing files with the CA certificates to verify the peer with when fetching or pushing over HTTPS. Can be overridden by the GIT_SSL_CAPATH environment variable.

http.maxRequests
    How many HTTP requests to launch in parallel. Can be overridden by the GIT_HTTP_MAX_REQUESTS environment variable. Default is 5.

http.minSessions
    The number of curl sessions (counted across slots) to be kept across requests. They will not be ended with curl_easy_cleanup() until http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this value will be capped at 1. Defaults to 1.

http.postBuffer
    Maximum size in bytes of the buffer used by smart HTTP transports when POSTing data to the remote system. For requests larger than this buffer size, HTTP/1.1 and Transfer-Encoding: chunked is used to avoid creating a massive pack file locally. Default is 1 MiB, which is sufficient for most requests.

http.lowSpeedLimit, http.lowSpeedTime
    If the HTTP transfer speed is less than http.lowSpeedLimit for longer than http.lowSpeedTime seconds, the transfer is aborted. Can be overridden by the GIT_HTTP_LOW_SPEED_LIMIT and GIT_HTTP_LOW_SPEED_TIME environment variables.

http.noEPSV
    A boolean which disables using of EPSV ftp command by curl. This can helpful with some "poor" ftp servers which don't support EPSV mode. Can be overridden by the GIT_CURL_FTP_NO_EPSV environment variable. Default is false (curl will use EPSV).

i18n.commitEncoding
    Character encoding the commit messages are stored in; git itself does not care per se, but this information is necessary e.g. when importing commits from emails or in the gitk graphical history browser (and possibly at other places in the future or in other porcelains). See e.g. git-mailinfo(1). Defaults to utf-8.

i18n.logOutputEncoding
    Character encoding the commit messages are converted to when running git log and friends.

imap
    The configuration variables in the imap section are described in git-imap-send(1).

init.templatedir
    Specify the directory from which templates will be copied. (See the "TEMPLATE DIRECTORY" section of git-init(1).)

instaweb.browser
    Specify the program that will be used to browse your working repository in gitweb. See git-instaweb(1).

instaweb.httpd
    The HTTP daemon command-line to start gitweb on your working repository. See git-instaweb(1).

instaweb.local
    If true the web server started by git-instaweb(1) will be bound to the local IP (127.0.0.1).

instaweb.modulepath
    The module path for an apache httpd used by git-instaweb(1).

instaweb.port
    The port number to bind the gitweb httpd to. See git-instaweb(1).

interactive.singlekey
    In interactive commands, allow the user to provide one-letter input with a single key (i.e., without hitting enter). Currently this is used only by the --patch mode of git-add(1). Note that this setting is silently ignored if portable keystroke input is not available.

log.date
    Set default date-time mode for the log command. Setting log.date value is similar to using git log's --date option. The value is one of the following alternatives: {relative,local,default,iso,rfc,short}. See git-log(1).

log.showroot
    If true, the initial commit will be shown as a big creation event. This is equivalent to a diff against an empty tree. Tools like git-log(1) or git-whatchanged(1), which normally hide the root commit will now show it. True by default.

mailmap.file
    The location of an augmenting mailmap file. The default mailmap, located in the root of the repository, is loaded first, then the mailmap file pointed to by this variable. The location of the mailmap file may be in a repository subdirectory, or somewhere outside of the repository itself. See git-shortlog(1) and git-blame(1).

man.viewer
    Specify the programs that may be used to display help in the man format. See git-help(1).

man.<tool>.cmd
    Specify the command to invoke the specified man viewer. The specified command is evaluated in shell with the man page passed as argument. (See git-help(1).)

man.<tool>.path
    Override the path for the given tool that may be used to display help in the man format. See git-help(1).

merge.conflictstyle
    Specify the style in which conflicted hunks are written out to working tree files upon merge. The default is "merge", which shows a <<<<<<< conflict marker, changes made by one side, a ======= marker, changes made by the other side, and then a >>>>>>> marker. An alternate style, "diff3", adds a ||||||| marker and the original text before the ======= marker.

merge.log
    Whether to include summaries of merged commits in newly created merge commit messages. False by default.

merge.renameLimit
    The number of files to consider when performing rename detection during a merge; if not specified, defaults to the value of diff.renameLimit.

merge.stat
    Whether to print the diffstat between ORIG_HEAD and the merge result at the end of the merge. True by default.

merge.tool
    Controls which merge resolution program is used by git-mergetool(1). Valid built-in values are: "kdiff3", "tkdiff", "meld", "xxdiff", "emerge", "vimdiff", "gvimdiff", "diffuse", "ecmerge", "tortoisemerge", "p4merge", "araxis" and "opendiff". Any other value is treated is custom merge tool and there must be a corresponding mergetool.<tool>.cmd option.

merge.verbosity
    Controls the amount of output shown by the recursive merge strategy. Level 0 outputs nothing except a final error message if conflicts were detected. Level 1 outputs only conflicts, 2 outputs conflicts and file changes. Level 5 and above outputs debugging information. The default is level 2. Can be overridden by the GIT_MERGE_VERBOSITY environment variable.

merge.<driver>.name
    Defines a human-readable name for a custom low-level merge driver. See gitattributes(5) for details.

merge.<driver>.driver
    Defines the command that implements a custom low-level merge driver. See gitattributes(5) for details.

merge.<driver>.recursive
    Names a low-level merge driver to be used when performing an internal merge between common ancestors. See gitattributes(5) for details.

mergetool.<tool>.path
    Override the path for the given tool. This is useful in case your tool is not in the PATH.

mergetool.<tool>.cmd
    Specify the command to invoke the specified merge tool. The specified command is evaluated in shell with the following variables available: BASE is the name of a temporary file containing the common base of the files to be merged, if available; LOCAL is the name of a temporary file containing the contents of the file on the current branch; REMOTE is the name of a temporary file containing the contents of the file from the branch being merged; MERGED contains the name of the file to which the merge tool should write the results of a successful merge.

mergetool.<tool>.trustExitCode
    For a custom merge command, specify whether the exit code of the merge command can be used to determine whether the merge was successful. If this is not set to true then the merge target file timestamp is checked and the merge assumed to have been successful if the file has been updated, otherwise the user is prompted to indicate the success of the merge.

mergetool.keepBackup
    After performing a merge, the original file with conflict markers can be saved as a file with a .orig extension. If this variable is set to false then this file is not preserved. Defaults to true (i.e. keep the backup files).

mergetool.keepTemporaries
    When invoking a custom merge tool, git uses a set of temporary files to pass to the tool. If the tool returns an error and this variable is set to true, then these temporary files will be preserved, otherwise they will be removed after the tool has exited. Defaults to false.

mergetool.prompt
    Prompt before each invocation of the merge resolution program.

notes.displayRef
    The (fully qualified) refname from which to show notes when showing commit messages. The value of this variable can be set to a glob, in which case notes from all matching refs will be shown. You may also specify this configuration variable several times. A warning will be issued for refs that do not exist, but a glob that does not match any refs is silently ignored.

    This setting can be overridden with the GIT_NOTES_DISPLAY_REF environment variable, which must be a colon separated list of refs or globs.

    The effective value of "core.notesRef" (possibly overridden by GIT_NOTES_REF) is also implicitly added to the list of refs to be displayed.

notes.rewrite.<command>
    When rewriting commits with <command> (currently amend or rebase) and this variable is set to true, git automatically copies your notes from the original to the rewritten commit. Defaults to true, but see "notes.rewriteRef" below.

notes.rewriteMode
    When copying notes during a rewrite (see the "notes.rewrite.<command>" option), determines what to do if the target commit already has a note. Must be one of overwrite, concatenate, or ignore. Defaults to concatenate.

    This setting can be overridden with the GIT_NOTES_REWRITE_MODE environment variable.

notes.rewriteRef
    When copying notes during a rewrite, specifies the (fully qualified) ref whose notes should be copied. The ref may be a glob, in which case notes in all matching refs will be copied. You may also specify this configuration several times.

    Does not have a default value; you must configure this variable to enable note rewriting.

    This setting can be overridden with the GIT_NOTES_REWRITE_REF environment variable, which must be a colon separated list of refs or globs.

pack.window
    The size of the window used by git-pack-objects(1) when no window size is given on the command line. Defaults to 10.

pack.depth
    The maximum delta depth used by git-pack-objects(1) when no maximum depth is given on the command line. Defaults to 50.

pack.windowMemory
    The window memory size limit used by git-pack-objects(1) when no limit is given on the command line. The value can be suffixed with "k", "m", or "g". Defaults to 0, meaning no limit.

pack.compression
    An integer -1..9, indicating the compression level for objects in a pack file. -1 is the zlib default. 0 means no compression, and 1..9 are various speed/size tradeoffs, 9 being slowest. If not set, defaults to core.compression. If that is not set, defaults to -1, the zlib default, which is "a default compromise between speed and compression (currently equivalent to level 6)."

pack.deltaCacheSize
    The maximum memory in bytes used for caching deltas in git-pack-objects(1) before writing them out to a pack. This cache is used to speed up the writing object phase by not having to recompute the final delta result once the best match for all objects is found. Repacking large repositories on machines which are tight with memory might be badly impacted by this though, especially if this cache pushes the system into swapping. A value of 0 means no limit. The smallest size of 1 byte may be used to virtually disable this cache. Defaults to 256 MiB.

pack.deltaCacheLimit
    The maximum size of a delta, that is cached in git-pack-objects(1). This cache is used to speed up the writing object phase by not having to recompute the final delta result once the best match for all objects is found. Defaults to 1000.

pack.threads
    Specifies the number of threads to spawn when searching for best delta matches. This requires that git-pack-objects(1) be compiled with pthreads otherwise this option is ignored with a warning. This is meant to reduce packing time on multiprocessor machines. The required amount of memory for the delta search window is however multiplied by the number of threads. Specifying 0 will cause git to auto-detect the number of CPU's and set the number of threads accordingly.

pack.indexVersion
    Specify the default pack index version. Valid values are 1 for legacy pack index used by Git versions prior to 1.5.2, and 2 for the new pack index with capabilities for packs larger than 4 GB as well as proper protection against the repacking of corrupted packs. Version 2 is the default. Note that version 2 is enforced and this config option ignored whenever the corresponding pack is larger than 2 GB.

    If you have an old git that does not understand the version 2 *.idx file, cloning or fetching over a non native protocol (e.g. "http" and "rsync") that will copy both *.pack file and corresponding *.idx file from the other side may give you a repository that cannot be accessed with your older version of git. If the *.pack file is smaller than 2 GB, however, you can use git-index-pack(1) on the *.pack file to regenerate the *.idx file.

pack.packSizeLimit
    The maximum size of a pack. This setting only affects packing to a file when repacking, i.e. the git:// protocol is unaffected. It can be overridden by the --max-pack-size option of git-repack(1). The minimum size allowed is limited to 1 MiB. The default is unlimited. Common unit suffixes of k, m, or g are supported.

pager.<cmd>
    Allows turning on or off pagination of the output of a particular git subcommand when writing to a tty. If --paginate or --no-pager is specified on the command line, it takes precedence over this option. To disable pagination for all commands, set core.pager or GIT_PAGER to cat.

pull.octopus
    The default merge strategy to use when pulling multiple branches at once.

pull.twohead
    The default merge strategy to use when pulling a single branch.

push.default
    Defines the action git push should take if no refspec is given on the command line, no refspec is configured in the remote, and no refspec is implied by any of the options given on the command line. Possible values are:

        • nothing do not push anything.

        • matching push all matching branches. All branches having the same name in both ends are considered to be matching. This is the default.

        • tracking push the current branch to its upstream branch.

        • current push the current branch to a branch of the same name.

rebase.stat
    Whether to show a diffstat of what changed upstream since the last rebase. False by default.

receive.autogc
    By default, git-receive-pack will run "git-gc --auto" after receiving data from git-push and updating refs. You can stop it by setting this variable to false.

receive.fsckObjects
    If it is set to true, git-receive-pack will check all received objects. It will abort in the case of a malformed object or a broken link. The result of an abort are only dangling objects. Defaults to false.

receive.unpackLimit
    If the number of objects received in a push is below this limit then the objects will be unpacked into loose object files. However if the number of received objects equals or exceeds this limit then the received pack will be stored as a pack, after adding any missing delta bases. Storing the pack from a push can make the push operation complete faster, especially on slow filesystems. If not set, the value of transfer.unpackLimit is used instead.

receive.denyDeletes
    If set to true, git-receive-pack will deny a ref update that deletes the ref. Use this to prevent such a ref deletion via a push.

receive.denyCurrentBranch
    If set to true or "refuse", git-receive-pack will deny a ref update to the currently checked out branch of a non-bare repository. Such a push is potentially dangerous because it brings the HEAD out of sync with the index and working tree. If set to "warn", print a warning of such a push to stderr, but allow the push to proceed. If set to false or "ignore", allow such pushes with no message. Defaults to "refuse".

receive.denyNonFastForwards
    If set to true, git-receive-pack will deny a ref update which is not a fast-forward. Use this to prevent such an update via a push, even if that push is forced. This configuration variable is set when initializing a shared repository.

receive.updateserverinfo
    If set to true, git-receive-pack will run git-update-server-info after receiving data from git-push and updating refs.

remote.<name>.url
    The URL of a remote repository. See git-fetch(1) or git-push(1).

remote.<name>.pushurl
    The push URL of a remote repository. See git-push(1).

remote.<name>.proxy
    For remotes that require curl (http, https and ftp), the URL to the proxy to use for that remote. Set to the empty string to disable proxying for that remote.

remote.<name>.fetch
    The default set of "refspec" for git-fetch(1). See git-fetch(1).

remote.<name>.push
    The default set of "refspec" for git-push(1). See git-push(1).

remote.<name>.mirror
    If true, pushing to this remote will automatically behave as if the --mirror option was given on the command line.

remote.<name>.skipDefaultUpdate
    If true, this remote will be skipped by default when updating using git-fetch(1) or the update subcommand of git-remote(1).

remote.<name>.skipFetchAll
    If true, this remote will be skipped by default when updating using git-fetch(1) or the update subcommand of git-remote(1).

remote.<name>.receivepack
    The default program to execute on the remote side when pushing. See option --receive-pack of git-push(1).

remote.<name>.uploadpack
    The default program to execute on the remote side when fetching. See option --upload-pack of git-fetch-pack(1).

remote.<name>.tagopt
    Setting this value to --no-tags disables automatic tag following when fetching from remote <name>

remote.<name>.vcs
    Setting this to a value <vcs> will cause git to interact with the remote with the git-remote-<vcs> helper.

remotes.<group>
    The list of remotes which are fetched by "git remote update <group>". See git-remote(1).

repack.usedeltabaseoffset
    By default, git-repack(1) creates packs that use delta-base offset. If you need to share your repository with git older than version 1.4.4, either directly or via a dumb protocol such as http, then you need to set this option to "false" and repack. Access from old git versions over the native protocol are unaffected by this option.

rerere.autoupdate
    When set to true, git-rerere updates the index with the resulting contents after it cleanly resolves conflicts using previously recorded resolution. Defaults to false.

rerere.enabled
    Activate recording of resolved conflicts, so that identical conflict hunks can be resolved automatically, should they be encountered again. git-rerere(1) command is by default enabled if you create rr-cache directory under $GIT_DIR, but can be disabled by setting this option to false.

sendemail.identity
    A configuration identity. When given, causes values in the sendemail.<identity> subsection to take precedence over values in the sendemail section. The default identity is the value of sendemail.identity.

sendemail.smtpencryption
    See git-send-email(1) for description. Note that this setting is not subject to the identity mechanism.

sendemail.smtpssl
    Deprecated alias for sendemail.smtpencryption = ssl.

sendemail.<identity>.*
    Identity-specific versions of the sendemail.* parameters found below, taking precedence over those when the this identity is selected, through command-line or sendemail.identity.

sendemail.aliasesfile, sendemail.aliasfiletype, sendemail.bcc, sendemail.cc, sendemail.cccmd, sendemail.chainreplyto, sendemail.confirm, sendemail.envelopesender, sendemail.from, sendemail.multiedit, sendemail.signedoffbycc, sendemail.smtppass, sendemail.suppresscc, sendemail.suppressfrom, sendemail.to, sendemail.smtpdomain, sendemail.smtpserver, sendemail.smtpserverport, sendemail.smtpuser, sendemail.thread, sendemail.validate
    See git-send-email(1) for description.

sendemail.signedoffcc
    Deprecated alias for sendemail.signedoffbycc.

showbranch.default
    The default set of branches for git-show-branch(1). See git-show-branch(1).

status.relativePaths
    By default, git-status(1) shows paths relative to the current directory. Setting this variable to false shows paths relative to the repository root (this was the default for git prior to v1.5.4).

status.showUntrackedFiles
    By default, git-status(1) and git-commit(1) show files which are not currently tracked by Git. Directories which contain only untracked files, are shown with the directory name only. Showing untracked files means that Git needs to lstat() all all the files in the whole repository, which might be slow on some systems. So, this variable controls how the commands displays the untracked files. Possible values are:

        • no - Show no untracked files

        • normal - Shows untracked files and directories

        • all - Shows also individual files in untracked directories.
        If this variable is not specified, it defaults to normal. This variable can be overridden with the -u|--untracked-files option of git-status(1) and git-commit(1).

    status.submodulesummary
        Defaults to false. If this is set to a non zero number or true (identical to -1 or an unlimited number), the submodule summary will be enabled and a summary of commits for modified submodules will be shown (see --summary-limit option of git-submodule(1)).

    tar.umask
        This variable can be used to restrict the permission bits of tar archive entries. The default is 0002, which turns off the world write bit. The special value "user" indicates that the archiving user's umask will be used instead. See umask(2) and git-archive(1).

    transfer.unpackLimit
        When fetch.unpackLimit or receive.unpackLimit are not set, the value of this variable is used instead. The default value is 100.

    url.<base>.insteadOf
        Any URL that starts with this value will be rewritten to start, instead, with <base>. In cases where some site serves a large number of repositories, and serves them with multiple access methods, and some users need to use different access methods, this feature allows people to specify any of the equivalent URLs and have git automatically rewrite the URL to the best alternative for the particular user, even for a never-before-seen repository on the site. When more than one insteadOf strings match a given URL, the longest match is used.

    url.<base>.pushInsteadOf
        Any URL that starts with this value will not be pushed to; instead, it will be rewritten to start with <base>, and the resulting URL will be pushed to. In cases where some site serves a large number of repositories, and serves them with multiple access methods, some of which do not allow push, this feature allows people to specify a pull-only URL and have git automatically use an appropriate URL to push, even for a never-before-seen repository on the site. When more than one pushInsteadOf strings match a given URL, the longest match is used. If a remote has an explicit pushurl, git will ignore this setting for that remote.

    user.email
        Your email address to be recorded in any newly created commits. Can be overridden by the GIT_AUTHOR_EMAIL, GIT_COMMITTER_EMAIL, and EMAIL environment variables. See git-commit-tree(1).

    user.name
        Your full name to be recorded in any newly created commits. Can be overridden by the GIT_AUTHOR_NAME and GIT_COMMITTER_NAME environment variables. See git-commit-tree(1).

    user.signingkey
        If git-tag(1) is not selecting the key you want it to automatically when creating a signed tag, you can override the default selection with this variable. This option is passed unchanged to gpg's --local-user parameter, so you may specify a key using any method that gpg supports.

    web.browser
        Specify a web browser that may be used by some commands. Currently only git-instaweb(1) and git-help(1) may use it.
