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.

# Cron only provides a limited environment.
# To simulate it to test run your scripts
# first add this to your cron:
* * * * * env > ~/cronenv
# This will export the limited cron environment to a file.
# Now launch a new shell using this file to test your scripts:
$ env - `cat ~/cronenv` /bin/sh 

# Tell it what email to send output to:
