git-mktag - Creates a tag object


git mktag < signature_file


Reads a tag contents on standard input and creates a tag object that can also be used to sign other objects.

The output is the new tag’s <object> identifier.

Tag Format

A tag signature file has a very simple fixed format: four lines of

object <sha1>
type <typename>
tag <tagname>
tagger <tagger>

followed by some optional free-form message (some tags created by older Git may not have tagger line). The message, when exists, is separated by a blank line from the header. The message part may contain a signature that Git itself doesn’t care about, but that can be verified with gpg.
