How do you revert to a specific tag in Git?

I know how to revert to older commits in a Git branch, but how do I revert back to a branch's state dictated by a tag? I envision something like this:

git revert -bytag "Version 1.0 Revision 1.5"

Is this possible?

Git tags are just pointers to the commit. So you use them the same way as you do HEAD, branch names or commit sha hashes. You can use tags with any git command that accepts commit/revision arguments. You can try it with git rev-parse tagname to display the commit it points to.

In your case you have at least these two alternatives:

1. Reset the current branch to specific tag:

    git reset --hard tagname
   

2. Generate revert commit on top to get you to the state of the tag:

    git revert tag
   

This might introduce some conflicts if you have merge commits though.

Use git reset:

git reset --hard "Version 1.0 Revision 1.5"

(assuming that the specified string is the tag).

You can use git checkout.

I tried the accepted solution but got an error, warning: refname '<tagname>' is ambiguous'

But as the answer states, tags do behave like a pointer to a commit, so as you would with a commit hash, you can just checkout the tag. The only difference is you preface it with tags/:

git checkout tags/<tagname>

If you are:

• sure about which commit you want to get back to
• get rid of all the commits after that
• apply changes to your remote

1. reset to a tag named reset-to-here

   git reset --hard reset-to-here
   

2. push your change to the remote forcing by +

   git push origin +master
