Adding Remotes
5:01Before you can "push" commits to another repository, you need to add it as a remote repo.
This time, we've made a change not in the
medals repo but in the myclone repo, so
0:00
let's change to that directory,
cd myclone.
0:04
Now let's take a look at what's changed,
git diff.
0:09
We realize that there was
no link to the gold.html or
0:12
the silver.html pages from the main page,
so we added links and saved the file.
0:15
Let's stage the changes,
git add medals.html,
0:21
and now let's commit them,
git commit -m "Add links".
0:27
That commit now appears in our history for
the myclone repository.
0:34
If we run git log,
we'll see the add links commit at the top.
0:37
Now as you might anticipate
from seeing the previous video,
0:43
this commit does not appear
in the medals repository.
0:46
Let's change to the parent directory, and
then back down to the medals subdirectory.
0:50
Now that we're in the medals repo,
let's run git log, and
0:56
there's no add links commit here.
1:00
And although we were able to run git pull
in the myclone repository to pull in
1:03
commits from the medals repo,
we can't pull from myclone to medals yet.
1:08
If we run git pull myclone,
we'll get the error,
1:12
myclone does not appear
to be a git repository.
1:19
When we cloned the medals repository
to the myclone repository,
1:23
medals was automatically set up
as a remote repo on myclone.
1:27
But the reverse isn't true, in fact,
1:31
we can try running git
remote from the medals repo.
1:33
git remote, and
we don't see any remote repos at all.
1:36
So we're going to need to add myclone
as a remote on the medals repo.
1:42
We can do this with the git
remote add command.
1:47
git remote add takes two arguments,
1:51
the first is the name we want
to give the remote repo.
1:54
We can use any name we want, but
generally it should be all lowercase.
1:57
In the myclone repo,
2:01
a default name of origin was used
to refer to the medals repo.
2:03
Medals wasn't cloned from myclone, though,
so that's probably not appropriate here.
2:06
Instead we'll just give it the same name
as the directory we cloned it to, myclone.
2:12
The second argument will usually be
the URL of the remote repository.
2:19
Since this remote repo is just another
directory on our local computer,
2:24
we'll give it the path to
that directory instead.
2:28
We can't just type myclone, though,
2:32
that would indicate the myclone directory
lives inside the medals directory.
2:34
We need to indicate the myclone
directory that lives alongside
2:40
the medals directory in
the parent directory.
2:43
So we type .., for
the parent directory, /myclone.
2:45
You can read that as the parent
directory's myclone subdirectory.
2:51
Okay, so we have a name for
2:56
the remote repo as well as the directory
path that we're using in place of a URL.
2:57
Let's hit Enter to run the command.
3:02
We won't see any output, but as usual,
that just means there were no errors.
3:04
Now let's try running git remote again.
3:09
This time we'll see a remote repo
with the name we specified, myclone.
3:12
So now we have a remote repo set
up in the medals repo as well.
3:17
Let's see if git pull works this time.
3:21
git pull, we still get a no remote
repository specified error.
3:23
Let's try specifying the remote
repository name, git pull myclone.
3:29
We get an error again, but it's not
myclone does not appear to be a git
3:36
repository, so at least this is progress.
3:40
The error says we didn't
specify a branch to pull from.
3:43
We won't be covering git branches
in this introductory course.
3:47
But you can see the teacher's notes
if you'd like more info about them.
3:51
We have to specify a branch name to
get this command to work, though.
3:55
You can get the current branch
name with the git branch command.
3:58
By default, git repositories start
with only one branch, named master.
4:04
Because we haven't created
any other branches,
4:09
our work in the myclone repo will be
on the master branch there as well.
4:12
So let's specify master as the branch name
to pull from, git pull myclone master.
4:16
That took a lot of setup, but
our command finally worked.
4:28
It pulls our new commit from the myclone
remote repo into the medals repo.
4:31
If we run git log,
we'll see the Add links commit at the top.
4:36
And if we run git log -p, it will show the
actual changes to the medals.html file.
4:42
So now you know how to
add a remote repo in git.
4:50
That's going to be important,
4:53
because the next remote you add
is going to be a GitHub repo.
4:54
We'll show you how to share your
work on GitHub in the next video.
