What if I forgot to add a file in my last commit?
git add file.js # the file that needed to be included
git commit --amend # amend the commit done before step 1 with the added file
This will add the file to the previous commit and replace it with a new commit.
This can be simplified into one command:
git commit --amend file.js
If the commit message doesn’t need to be updated:
git commit --amend --no-edit file.js
If all the edited files need to be added to the last commit:
git commit --amend --no-edit --all
