Git - tagging
A lightweight tag in git is just a bookmark of a specific commit.
To create a tag just run the command:
$ git tag my_tag_name -m "Tag message"
Do not use spaces in tag name.
To list tags:
$ git tag -ln
my_tag_name Tag message
You can see the tag data along with the commit that was tagged by using the git show command:
$ git show my_tag_name
