redisFind key by value in Redis

This should be used for debugging purposes only:

for k in $(redis-cli KEYS '*'); do echo $k \"$(redis-cli GET $k)\"; done | grep "125"ctrl + cgithub

`redis-cli` launch Redis CLI interface in interactive mode	`KEYS '*'` finds all keys on Redis server
`do echo $k` for every key we will print key name	`redis-cli GET $k` for every key we'll also get and print key value
`grep "125"` and then we'll filter by required value (`125` in our case)

for k in $(redis-cli KEYS '*'); do echo $k \"$(redis-cli GET $k)\"; done | grep "125"

test "125"
