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

NAME top

       git-mktag - Creates a tag object with extra validation

SYNOPSIS top

       git mktag

DESCRIPTION top

       Reads a tag’s 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 by 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> variable:

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

OPTIONS top

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

TAG FORMAT top

       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 a 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.
