How can I delete all of my Git stashes at once?

Question

How can I delete all of my Git stashes at once?

Specifically I mean, with typing in one command.

Answer 1

I wanted to keep a few recent stashes, but delete everything else.

Because all stashes get renumbered when you drop one, this is actually easy to do with while. To delete all stashes older than stash@{19}:

while git stash drop 'stash@{20}'; do true; done
