How to change your commit messages in Git?

At some point you’ll find yourself in a situation where you need edit a commit message. That commit might already be pushed or not, be the most recent or burried below 10 other commits, but fear not, git has your back 🙂.

Not pushed + most recent commit:

git commit --amend

This will open your $EDITOR and let you change the message. Continue with your usual git push origin master.

#  This is a little script to populate Firefox Sync with
#  fake password records.  Use it like so:
#
#    $> pip install PyFxA syncclient cryptography
#    $> python ./upload_fake_passwords.py 20
#
#  It will prompt for your Firefox Account email address and
#  password, generate and upload 20 fake password records, then
#  sync down and print all password records stored in sync.
