It’s called changes. Here’s how I tend to use it: # editing a file in a Git project $ git add $FILE_I_CHANGED $ changes It needs to be located in a PATH-included directory, I usually put mine into an own folder called ~/local/bin. Not For Team Use I wouldn’t run it on a non-private non-early-stage project. All it does, is create a new commit with the message “changes” and push it.
