Remove Git tags based on regular expression, and remove from remote

remove-tags.sh

#!/bin/bash

for i in $( git tag | grep ^tag_name_pattern ); do
    #echo item: $i
    git tag -d $i
    #git push origin :refs/tags/$i
    git push --delete origin $i
done

# or on one line
for i in $( git tag | grep ^tag_name_pattern ); do git tag -d $i; git push --delete origin $i; done

# even faster
git push origin --delete $(git tag -l | grep ^pattern) && git tag -d $(git tag -l | grep ^pattern)
