add new remotes and git remote rm
to delete existing ones.
Git has two commands to update itself from a remote repository.
git fetch
will syncronize you with another repo, pulling down any data
- that you do not have locally and giving you bookmarks to where each branch on
+ that you do not have locally and giving you bookmarks to where each branch on
that remote was when you syncronized. These are called "remote branches" and are
- identical to local branches except that Git will not allow you to check them out -
+ identical to local branches except that Git will not allow you to check them out -
however, you can merge from them, diff them to other branches, run history logs on
them, etc. You do all of that stuff locally after you syncronize.
Assuming you have a remote all set up and you want to pull in updates, you
would first run git fetch [alias]
to tell Git to fetch down all the
data it has that you do not, then you would run git merge [alias]/[branch]
- to merge into your current branch anything new you see on the server
+ to merge into your current branch anything new you see on the server
(like if someone else has pushed in the meantime). So, if I were working on my
Hello World project with several other people and I wanted to bring in any changes
that had been pushed since I last connected, I would do something like this:

You can see the mapping that Git makes. The 'master' branch on the remote
repository becomes a branch named 'github/master' locally. That way now I can
merge the 'master' branch on that remote into my local 'master' branch by running
git merge github/master
. Or, I can see what new commits are on that
- branch by running git log github/master ^master
. If your remote

is named 'origin' it would be origin/master
instead. Almost any
command you would run using local branches you can use remote branches with too.
git fetch --all

To share the cool commits you've done with others, you need to push your

git push [alias] [branch]
which will attempt to make your [branch]

our 'master' branch to the new 'github' remote we created earlier.
The last major issue you run into with pushing to remote branches is the
case of someone pushing in the meantime. If you and another developer clone
- at the same time, you both do commits, then she pushes and then you try to

push, Git will by default not allow you to overwrite her changes. Instead,
it basically runs git log
on the branch you're trying to push and
makes sure it can see the current tip of the servers branch in your pushes
history. If it can't see what is on the server in your history, it concludes
that you are out of date and will reject your push. You will rightly have to

account.
This is what happens when you try to push a branch to a remote branch that has been updated in the meantime:
