Github command cheatsheet

Branching

If another_branch already exists locally and you are not on this branch, then git checkout another_branch switches to the branch.

If another_branch does not exist but origin/another_branch does, then git checkout another_branch is equivalent to git checkout -b another_branch origin/another_branch;git branch -u origin/another_branch. That's to create another_branch from origin/another_branch and set origin/another_branch as the upstream of another_branch.

If neither exists, git checkout another_branch returns error.
