Redis – Strings

”;

Redis strings commands are used for managing string values in Redis. Following is the syntax for using Redis string commands.

redis 127.0.0.1:6379> COMMAND KEY_NAME

redis 127.0.0.1:6379> SET tutorialspoint redis 
OK 
redis 127.0.0.1:6379> GET tutorialspoint 
"redis"

In the above example, SET and GET are the commands, while tutorialspoint is the key.
