Typically, you would use git rebase to:
- Edit previous commit messages
- Combine multiple commits into one
- Delete or revert commits that are no longer necessary
Warning: Because changing your commit history can make things difficult for everyone else using the repository, it's considered bad practice to rebase commits when you've already pushed to a repository. To learn how to safely rebase on your GitHub Enterprise Server instance, see "About pull request merges."
Rebasing commits against a branch
To rebase all the commits between another branch and the current branch state, you can enter the following command in your shell (either the command prompt for Windows, or the terminal for Mac and Linux):
$ git rebase --interactive OTHER-BRANCH-NAME
Rebasing commits against a point in time
To rebase the last few commits in your current branch, you can enter the following command in your shell:
$ git rebase --interactive HEAD~7
Commands available while rebasing
There are six commands available while rebasing:
pickpicksimply means that the commit is included. Rearranging the order of thepickcommands changes the order of the commits when the rebase is underway. If you choose not to include a commit, you should delete the entire line.reword- The
rewordcommand is similar topick, but after you use it, the rebase process will pause and give you a chance to alter the commit message. Any changes made by the commit are not affected. edit- If you choose to
edita commit, you'll be given the chance to amend the commit, meaning that you can add or change the commit entirely. You can also make more commits before you continue the rebase. This allows you to split a large commit into smaller ones, or, remove erroneous changes made in a commit. squash- This command lets you combine two or more commits into a single commit. A commit is squashed into the commit above it. Git gives you the chance to write a new commit message describing both changes.
fixup- This is similar to
squash, but the commit to be merged has its message discarded. The commit is simply merged into the commit above it, and the earlier commit's message is used to describe both changes. exec- This lets you run arbitrary shell commands against a commit.
