git tag

By  on  

git tag is used to pin down a given revision as significant, often for the purpose of officially releasing code.  Once a tag is created, it's often referred to by build and deploy scripts instead of the tag's represented commit.  Tagging revisions  and deleting tags in git is easy -- let me show you how to do it!

Tagging a Revision

Assuming you're at the revision you want to tag, git tag {tagname} is the format to use:

git tag 0.1.0

You can name the tag whatever you'd like but oftentimes the tag is named via a release number system like 0.1.0, 0.1.1, 0.2.0, and so on.

Pushing Tags

You can create a tag locally but they aren't automatically pushed to the remote repository -- you must do that manually:

git push --tags

Don't forget to push your tags!

Deleting Tags

If you want to delete or remove a tag from history, you may do so using the -d flag:

git tag -d 0.1.0
git push origin :refs/tags/0.1.0

Unless you do a fair bit of tagging, you likely have to look back on a few of the commands when the time comes -- at least I do!

    Speaking of Tags, here is an one-liner that will automatically checkout the latest tag of a git repository.

    git checkout $(git describe --tags $(git rev-list --tags --max-count=1))

Wrap your code in <pre class="{language}"></pre> tags, link to a GitHub gist, JSFiddle fiddle, or CodePen pen to embed!
