## Name

opendb — Closes the current database file and opens database.g.

## Synopsis

`opendb` [-f] [`database.g`]

## DESCRIPTION

Closes the current database file and opens database.g. If database.g is not found, the current database is left open. If database.g is not specified on the command line, the name of the current database file is returned.

If the -f option is specified and the database.g is a v4 geometry database, the file will be read with a flipped binary endianness encoding. This is useful for binary-incompatible v4 geometry files that were created on a different platform type.

Binary-incompatible v4 geometry database files that can be auto-detected will be automatically converted if all resulting matrices are valid.

## EXAMPLES

The first example shows the use of the opendb command to close the current database file and open the one specified. The second example shows the use of the command with no database name, which returns the name of the current database file.

Example 1. Close the current database and open another one.

`mged>``opendb model.g`

Closes the current database file and opens model.g.

Example 2. Return the name of the current database file.

`mged>``opendb`

Returns the name of the current database file.

Example 3. Open and upgrade a binary-incompatible v4 file.

`mged>``opendb -f model.g` `mged>``dbupgrade`

Closes any currently open database and opens model.g as a binary-incompatible v4 geometry database.
