git undo last commit

This is a git command I use quite often, so I searched a little about the different options and their effects:

Command	Commit History	Staging Area	Working Directory
git reset HEAD~	Removes last commit	Unstages changes	Keeps changes
git reset --soft HEAD~	Removes last commit	Keeps changes staged	Keeps changes
git reset --hard HEAD~	Removes last commit	Discards all changes	Discards all changes

• HEAD~ refers to the commit just before the current HEAD (i.e., the previous commit).

What happens when you run git reset HEAD~:

• The branch pointer (HEAD) is moved back by one commit, undoing the latest commit from your branch history.
• The changes from that commit are unstaged, but you can still see them in your working directory
