arc: Update Git commit messages after review.
$ arc amend
try on your machine
The command arc amend
is typically used in a version control system called Phabricator or Diffusion and is used to amend or modify an existing commit.
When you make changes to a codebase, you often create multiple commits to track the changes you make over time. However, sometimes you may want to make changes to a commit that you have already created. Instead of creating a new commit for these changes, arc amend
allows you to modify the existing commit.
Here's how the arc amend
command works:
- You make changes to your code files as necessary.
- After making the changes, stage the modified files using a command like
git add .
orhg add
. - Run
arc amend
command. This will bring up an editor with the commit message of the previous commit (the one you want to amend). - Modify the commit message if needed or simply save and close the editor if you don't want to change the message.
- The changes you made will be incorporated into the previous commit, effectively amending it.
arc amend
is useful when you want to add or modify small changes to a commit without creating a new one. It helps in keeping the commit history clean and avoids creating unnecessary commit noise.

never run a command you are not sure if it is safe.
