git tag - How do I read tagger information from a git tag? -

so far have:

git rev-parse <tagname> | xargs git cat-file -p 

but isn't easiest thing parse. hoping similar git-log's --pretty option grab info need.

any ideas? thanks

a more direct way of getting same info is:

git cat-file tag <tagname> 

this uses single command , avoids pipe.

i used in bash script follows:

if git rev-parse $tag^{tag} -- &>/dev/null     # annotated tag     commit=$(git rev-parse $tag^{commit})     tagger=($(git cat-file tag $tag | grep '^tagger'))     n=${#tagger} # number of fields     date=${tagger[@]:$n-2:2} # last 2 fields     author=${tagger[@]:1:$n-3} # first , last 2     message=$(git cat-file tag $tag | tail -n+6) elif git rev-parse refs/tags/$tag -- &>/dev/null     # lightweight tag - commit,     commit=$(git rev-parse $tag^{commit}) else     echo "$tag: not tag" >&2 fi
