git commit --amend --only -m is a Git command that allows you to amend the last commit by updating only specific files in the commit and changing the commit message. The --only option specifies that only certain files should be updated, and the -m option allows you to provide a new commit message.

$ git commit --amend --only -m 'xxxxxxx'
