git change branch
[git checkout "branch_name"]
is another way to say:
[git checkout -b branch_name origin/branch_name]
in case "branch_name" exists only remotely.
[git checkout -b branch_name origin/branch_name] is useful in case you have multiple remotes.
Regarding [git checkout origin 'another_branch'] I'm not sure this is possible, AFAK you can do this using "fetch" command -- [git fetch origin 'another_branch']
Rename a local and remote branch in git
Rename your local branch. If you are on the branch you want to rename: git branch -m new-name. ...
Delete the old-name remote branch and push the new-name local branch. git push origin :old-name new-name.
Reset the upstream branch for the new-name local branch. Switch to the branch and then: git push origin -u new-name.
