Just a quick one.

Say you have a repository with many remotes. Don’t roll your eyes; it’s very likely if you have many collaborators, or if you’re tracking a popular open source project. To pull down all available changes at once try this:

git fetch --all

No surprise about what it does.

Of course, this is a fetch, not a pull, which is a combination of git fetch and git merge, so after this command, don’t expect that your branches have been magically updated. I’m not a big fan of pull; I much prefer to fetch all changes and then explicitly merge with a chosen branch. In my case this works because I don’t have many tracking branches, because I find I can work just as well with the remote branches directly.
