Question

AFAIK, git push --tag pushes every tags under refs/tags to remote. I want to know if there is a way in git to only push some tags that matches a wildcard or regexp?

For example, my repo has tag v1.0, v1.1, v2.0 and v2.1. I want to only push v2.*. I tried

git push <repo> refs/tags/v2.*

and got error

fatal: remote part of refspec is not a valid name in refs/tags/v2.*

Of course, I can always do

cd .git && ls refs/tags/v2.* | xargs git push <repo>

But this does not smell gity.

Answer 1

git tag | grep '^v2\.' | xargs --no-run-if-empty  git push <repo>

• .git may not be directory, it may not be there at all. Submodules have there file pointing to root repository. Or you can have GIT_DIR set to somewhere else.
• When no tags match your criteria, you do not want to do the push.
