Tag the last commit

Unless you select the -s flag for a signed tag, the tag will be a lightweight, unsigned tag by default. There are also some differences with lightweight tags:

  • When you use git tag <tagname>, Git will create a tag at the current revision but will not prompt you for an annotation. It will be tagged without a message.
  • When you use git tag -a <tagname>, Git will prompt you for an annotation unless you have also used the -m flag to provide a message.
  • When you use git tag -a -m <msg> <tagname>, Git will tag the commit and annotate it with the provided message.
  • When you use git tag -m <msg> <tagname>, Git will behave as if you passed the -a flag for annotation and use the provided message.

Basically, it just amounts to whether you want the lightweight tag to have an annotation associated with it or not.

List all tags along with the full message git tag -n prints the first line of the annotation

Remove a tag with git tag -d <tag>

and you would remove it from remote repository by doing git push origin :<tag>
