Being Code Expert: GET command in redis

GET key

This command get the value of the specified key. If the key does not exist the special value 'nil' is returned.

If the value stored at the key is not a string an error is returned because GET can only handle string values.

"1000"

Output

Example 2: When the key is not present

redis:6379> GET redisKey
