GIT-MKTAG(1)                                 Git Manual                                 GIT-MKTAG(1)



NAME
       git-mktag - Creates a tag object with extra validation

SYNOPSIS
       git mktag


DESCRIPTION
       Reads a tag contents on standard input and creates a tag object. The output is the new tag’s
       <object> identifier.

       This command is mostly equivalent to git-hash-object(1) invoked with -t tag -w --stdin. I.e.
       both of these will create and write a tag found in my-tag:

           git mktag <my-tag
           git hash-object -t tag -w --stdin <my-tag

       The difference is that mktag will die before writing the tag if the tag doesn’t pass a git-
       fsck(1) check.

       The "fsck" check done mktag is stricter than what git-fsck(1) would run by default in that
       all fsck.<msg-id> messages are promoted from warnings to errors (so e.g. a missing "tagger"
       line is an error).

       Extra headers in the object are also an error under mktag, but ignored by git-fsck(1). This
       extra check can be turned off by setting the appropriate fsck.<msg-id> varible:

           git -c fsck.extraHeaderEntry=ignore mktag <my-tag-with-headers

OPTIONS
       --strict
           By default mktag turns on the equivalent of git-fsck(1) --strict mode. Use --no-strict to
           disable it.

TAG FORMAT
       A tag signature file, to be fed to this command’s standard input, has a very simple fixed
       format: four lines of

           object <hash>
           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 it 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.
