Delete batches of tags in git

List tags

To list all tags, run

git tag

To list tags matching a pattern, use

git tag -l name_pattern 

For example, to list all tags with a name that begins with Release

git tag -l Release*

Delete tags locally

To delete a single tag

git tag -d name_of_tag

To delete multiple tags

git tag -d name_of_tag1 name_of_tag2

To delete all tags locally

git tag | xargs git tag -d  

(xargs takes the output from the first command and passes it as argument to the next)

To delete all tags that matches a name pattern

git tag -l Release* | xargs git tag -d

Delete tags on the remote

Assuming the remote is named origin and you want to delete all release tags for the 1.x and 2.x releases

git tag -l {Release/1.*,Release/2.*} | xargs git push --delete origin

REMEMBER to make sure that your pattern ONLY matches the tags that you want to delete. Inspect the result from the listing of matched tags before piping them to the next command.
