Unstaging Changes
1:51Staged a file, but decided you don't want to commit it? We'll show you how to unstage it.
Everybody makes mistakes,
including long time Git users.
0:00
Don't worry,
0:03
Git offers ways to undo almost every
mistake you could possibly make.
0:04
Some of those undo operations are easier
to understand than others, but
0:08
there is almost always an undo.
0:12
Let's suppose we've been
asked to advertise a 100%
0:14
off sale on our site's main page.
0:17
Running git diff shows our changes.
0:19
We've added a level one header
announcing our 100% off sale.
0:22
Let's stage our changes.
0:25
git add medals.html.
0:28
Now suppose we get word that
the store manager doesn't
0:33
want to do the 100% off sale anymore.
0:35
Well, what can we do?
0:38
We've already staged the code
to announce the sale.
0:39
Let's try running git status.
0:42
We'll see our staged medal.html file,
0:46
and the answer to our problem will
be right there in the output.
0:49
It says use git reset HEAD and
the file name to unstage.
0:52
So let's try that.
0:57
git reset HEAD.
0:58
HEAD needs to be in all caps, medals.html.
1:02
Now let's run git status again.
1:07
And we'll see that there's no more
changes to the committed section.
1:10
Instead, the medals.html file is back in
the changes not staged for commit section.
1:14
Normally, files transition from the
modified to the staged state, but we've
1:21
just taken a staged file and transitioned
it back to the modified state.
1:26
Now, here's the important
part to remember.
1:30
You don't have to remember this git
reset HEAD command if you don't want to.
1:33
If you ever have staged changes
that you want to unstage,
1:37
just remember to run git status, and it
will show you the command you need to run.
1:41
If you'd like to know more
about the git reset command,
1:46
we'll have more info in
the teacher's notes.
