Git protip: fix last commit with "--amend"

Adding a forgotten file

The most common case is forgetting to add a file to your commit, most of the time because it was untracked and you just went with the -a option that only adds already tracked / known files to Git: git commit -am '…'.

To fix this, you’ll have to:

• add the file(s) to the stage: git add <les-chemins>;
• cancel and replace the commit: git commit --amend.

Rewording the commit message

Let them who never made a typo or forgot an important reference like a ticket number in a commit message cast the first stone! Personally, I’m terrible at this.

When that happens, you’ll have to:

• check that your stage is empty (you don’t want to add stuff to the updated commit);
• run the git commit --amend command, possibly with the message “on the fly” if you want to rewrite it entirely (git commit --amend -m 'New message').
