What about Tags?

Let’s cover “off tags” really quickly while we’re here.

Tags#

Tags are the same as branches, except they do not have history. They point to a particular commit, but it doesn’t change (unless you force a change, or delete it).

How to apply tags?#

You can tag something where you are:

1   git tag i_was_here

Or you can tag wherever a branch pointer is pointed at in your repository, even if you are not on it:

2   git checkout e36355ed00ac3af009d7113a9dd281c269a79afd
3   git branch -f newfeature

The -f flag means --force. If a branch of newfeature already exists, then Git will not allow you to override it unless you use the -f flag.

4   git checkout master
5   git tag remember_to_tell_bob_to_rewrite_this newfeature

Use git tag to confirm that the tag now exists within the repository.
