Commit changes into a new revision.


brz commit [SELECTED…]


Set the author’s name, if it’s different from the committer.


Link to a related bug. (see “brz help bugs”).


Manually set a commit time using commit date format, e.g. ‘2009-10-10 08:00:00 +0100’.

-x ARG, --exclude=ARG

Do not consider changes made to a given path.


Take commit message from this file.


Mark a bug as being fixed by this revision (see “brz help bugs”).

-h, --help

Show help message.


Perform a local commit in a bound branch. Local commits are not pushed to the master branch until a normal commit is performed.


When committing to a foreign version control system do not push data that can not be natively represented.

-m ARG, --message=ARG

Description of the new revision.

-q, --quiet

Only display errors and warnings.

-p, --show-diff

When no message is supplied, show the diff along with the status summary in the message editor.


Refuse to commit if there are unknown files in the working tree.


Commit even if nothing has changed.


Show usage message and options.

-v, --verbose

Display more information.


An explanatory message needs to be given for each commit. This is often done by using the –message option (getting the message from the command line) or by using the –file option (getting the message from a file). If neither of these options is given, an editor is opened for the user to enter the message. To see the changed files in the boilerplate text loaded into the editor, use the –show-diff option.

By default, the entire tree is committed and the person doing the commit is assumed to be the author. These defaults can be overridden as explained below.

Selective commits

If selected files are specified, only changes to those files are committed. If a directory is specified then the directory and everything within it is committed.

When excludes are given, they take precedence over selected files. For example, to commit only changes within foo, but not changes within foo/bar:

brz commit foo -x foo/bar

A selective commit after a merge is not yet supported.

Custom authors

If the author of the change is not the same person as the committer, you can specify the author’s name using the –author option. The name should be in the same format as a committer-id, e.g. “John Doe <>”. If there is more than one author of the change you can specify the option multiple times, once for each author.


A common mistake is to forget to add a new file or directory before running the commit command. The –strict option checks for unknown files and aborts the commit if any are found. More advanced pre-commit checks can be implemented by defining hooks. See brz help hooks for details.

Things to note

If you accidentally commit the wrong changes or make a spelling mistake in the commit message say, you can use the uncommit command to undo it. See brz help uncommit for details.

Hooks can also be configured to run after a commit. This allows you to trigger updates to external systems like bug trackers. The –fixes option can be used to record the association between a revision and one or more bugs. See brz help bugs for details.
