You can undo git add
before commit with
git reset <file>
which will remove it from the current index (the "about to be committed" list) without changing anything else.
You can use
git reset
without any file name to unstage all due changes. This can come in handy when there are too many files to be listed one by one in a reasonable amount of time.
In old versions of Git, the above commands are equivalent to git reset HEAD <file>
and git reset HEAD
respectively, and will fail if HEAD
is undefined (because you haven't yet made any commits in your repository) or ambiguous (because you created a branch called HEAD
, which is a stupid thing that you shouldn't do).
