redis-cli [options] KEYS "prefix:*" | xargs redis-cli [options] DEL

@peterpoliwoda you can do the following:

redis-cli -h <HOST> -p <PORT> -a <PASSWORD> --scan --pattern "patter*n" | xargs redis-cli -h <HOST> -p <PORT> -a <PASSWORD> unlink

Using unlink is better then using del as stated in: https://redis.io/commands/unlink

Thanks, it did work.

If your keys have any escape characters you need to change the xargs delimiter:

redis-cli --scan --pattern "horizon:failed:*" | xargs -n 1 -d '\n' redis-cli DEL

that's my case, it worked - thanks a lot @jessecurry

How do I achieve the same using the redis pypi package ? Right now I'm using r.delete(*r.keys("someKey_*"))
