# git-mktag(1) Manual Page

## NAME

git-mktag - Creates a tag object

## SYNOPSIS

    git mktag < signature_file

## DESCRIPTION

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.
