# shell_default

### MODULE

shell_default

### MODULE SUMMARY

Customizing the Erlang Environment

### DESCRIPTION

The functions in shell_default are called when no module name is given in a shell command.

Consider the following shell dialogue:

    1 > lists:reverse("abc").
    "cba"
    2 > c(foo).
    {ok, foo}

In command one, the module lists is called. In command two, no module name is specified. The shell searches the modules user_default followed by shell_default for the function foo/1.

shell_default is intended for "system wide" customizations to the shell. user_default is intended for "local" or individual user customizations.

### Hint

To add your own commands to the shell, create a module called user_default and add the commands you want. Then add the following line as the first line in your .erlang file in your home directory.

    code:load_abs("$PATH/user_default").

$PATH is the directory where your user_default module can be found.
