How to change a Git commit message after push

To change a Git commit message after the commit has been pushed

• Open a terminal in the repository folder
• Use the interactive rebase command to retrieve the specified number of recent commit messages

git rebase -i HEAD~3

• The list of the recent commits appears in your default text editor

• Replace the word pick with reword in the lines you want to change, save and close the file.
• A new text file opens for each selected commit message. Edit the messages, save and close the files.

• Safe force push the updated commits with

git push --force-with-lease

This command will abort if there was a change in the repository since the original commit.
