In redis, how do i remove keys?

Question

I want to remove keys that match "user*".

how do I do that in redis command line?

Answer 1

When using the oneliner, you can edit the pattern in case it escapes specific characters. For instance, to delete patterns like '\b test \b' use:

redis-cli --raw KEYS '\\b*' | sed 's/\\b/\\\\b/g' | xargs redis-cli del

Answer 2

Using awk, find all matching keys from redis using redis-cli KEYS command and pipe to redis-cli DEL command.

redis-cli KEYS "user*"  | awk '{ system("redis-cli DEL " $1) }'
