Undoing things on git

git.sh

git reset --soft HEAD^ # when you just committed something you didn't mean to and you want to change the contents and the message
git commit --amend # when you want to change the commit message you just made
git reset file # when you have a file staged for delete that you want to unstage
git checkout file # when you want to restore that file you unstaged file to it's original version
git reset HEAD file # when you want to unstage a staged change
git reset --soft "HEAD^" # when you just committed something, but you want to undo the commit and revert everything to how it was staged before the commit
