Script to delete all tags both locally and remotely

git-deletealltags.bsh

for t in `git tag`
do
    git push origin :$t
    git tag -d $t
done

Very useful for cleaning up after testing some CI tools.

git tag -l | xargs -n 1 git push --delete origin

fatal: --delete doesn't make sense without any refs

@jmrobison, thanks, worked!

For the issue with --delete doesn't make sense without any refs here's how I delete all the tags for 1.3.* :
git ls-remote --tags origin | awk '/^(.*)(1\.3\.\d+)$/ {print ":" $2}' | xargs git push origin
