GIT-SQUASH-BRANCH(1)

NAME
git-squash-branch - Takes all commits in a single branch and replaces them with a single commit.

SYNOPSIS

git squash-branch [-m <message>]

DESCRIPTION

git squash-branch is a simple helper command. It takes all the commits on the current branch from the merge_base to HEAD, and reduces them to a single commit. The new commit will contain a summary of all the commits which were squashed, preceded by a header message indicating that it’s the result of a squash (or the message you pass on the command line.).

Squashing branches is useful when trying to rebase-update over branches which were pushed to their upstream (or committed by the Commit Queue), and then conflicting changes landed in upstream on top of the push/commit. If you know that your branch was committed but git-rebase-update(1) isn’t able to automatically clean it, you can squash the troublesome branch before git rebase-update, and then when git rebase-update presents the conflict, you can verify that the conflict diff is what you expected (and then skip it with git rebase --skip).

OPTIONS

-m <message>, --message=<message>
    Optional message to use for the first line of the squashed commit. If omitted, it defaults to "git squash commit for <branch>.".
