How can I edit my last commit message?

Changing the message in your last commit

You may find you've just created a new commit, but you want to modify the message.

Simply navigate to your project's directory via the command prompt, and type the following command, followed by the enter key:

$ git commit --amend

You'll be redirected to your text editor to edit the message. The message will be at the very top of the screen; simply edit it:

New commit message

# Please enter the commit message for your changes. Lines starting
# with '#' will be ignored, and an empty message aborts the commit.
#
# Date:      Thu May 16 11:47:16 2019 +0100
#
# On branch my_new_branch
# Your branch is up to date with 'origin/my_new_branch'.
#
# Changes to be committed:
#       new file:   newfile
#

Then, press ctrl + x followed by y and the enter key.
