Redis-cli && bash find keys with empty values -

how can find elements in redis empty have keys this:

setting:1 setting:2 setting:442 

etc

how can search redis-cli bash script command if key contains empty value redis-cli keys \* | xargs -l 1 redis-cli get grep , check if value empty

found solution

redis-cli keys "settings:*" | xargs -l 1 redis-cli 

the notion of empty key in redis non-existent - there no empty keys in redis. if key "becomes" empty (e.g. list popped final element), key not exist in redis anymore. here's example:

foo@bar:~$ redis-cli  127.0.0.1:6379> exists foo (integer) 0 127.0.0.1:6379> rpush foo bar (integer) 1 127.0.0.1:6379> exists foo (integer) 1 127.0.0.1:6379> lpop foo "bar" 127.0.0.1:6379> exists foo (integer) 0 127.0.0.1:6379>
