One annoying thing about git, is if you push a new local branch to a remote repository and forget the -u argument (short for --set-upstream), it does not automatically set the local branch to track the remote. I forget to include this argument most of the time.
So, later on, you'll probably want to pull changes down from the remote and you'll end up seeing something similar to this
➜ store git:(zendesk) git pull --rebase [48/53]There is no tracking information for the current branch. Please specify which branch you want to rebase against. See git-pull(1) for details git pull <remote> <branch> If you wish to set tracking information for this branch you can do so with: git branch --set-upstream-to=origin/<branch> zendesk
Now it's not that hard to type out the suggested command above to set the upstream branch, but I got sick of having to do it so often, and I have given up trying to remember -u, so I created a git alias to automate things and save some keystrokes.
In your ~/.gitconfig under the alias section, add this
sup = !git branch --set-upstream-to=origin/`git symbolic-ref --short HEAD`
You can use the alias by issuing the following command in your terminal
$ git sup
This will look at the current branch and set its upstream to origin/branchname
If you tend to use another remote name other than origin, change the alias accordingly.
I have a few other useful aliases which you can checkout (hah, sorry :)) in my full gitconfig.
