Redis Strings (String)

Commands related to the Redis string data type are used to manage Redis string values. The basic syntax is as follows:

Syntax

redis 127.0.0.1:6379> COMMAND KEY_NAME

Example

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

In the above example, we used the SET and GET commands with the key tutorialprokey.

Redis String Commands

The table below lists commonly used Redis string commands:

Number Command and Description
1 SET key value <br>Sets the value of a key.
2 GET key <br>Gets the value of a key.
3 GETRANGE key start end <br>Returns a substring of the string value stored at key.
4 GETSET key value <br>Sets the string value of a key and returns its old value.
5 GETBIT key offset <br>Gets the bit at the specified offset in the string value stored at key.
6 MGET key1 [key2..] <br>Gets the values of all given keys.
7 SETBIT key offset value <br>Sets or clears the bit at the specified offset in the string value stored at key.
8 SETEX key seconds value <br>Sets the value and expiration of a key.
9 SETNX key value <br>Sets the value of a key only if the key does not exist.
10 SETRANGE key offset value <br>Overwrites part of the string value stored at key, starting at the specified offset.
11 STRLEN key <br>Returns the length of the string value stored at key.
12 MSET key value [key value ...] <br>Sets multiple key-value pairs simultaneously.
13 MSETNX key value [key value ...] <br>Sets multiple key-value pairs only if none of the keys exist.
14 PSETEX key milliseconds value <br>Similar to SETEX, but sets the expiration time in milliseconds.
15 INCR key <br>Increments the integer value stored at key by one.
16 INCRBY key increment <br>Increments the value stored at key by a given increment.
17 INCRBYFLOAT key increment <br>Increments the value stored at key by a given floating-point increment.
18 DECR key <br>Decrements the integer value stored at key by one.
19 DECRBY key decrement <br>Decrements the value stored at key by a given decrement.
20 APPEND key value <br>If the key already exists and is a string, the APPEND command appends the specified value to the end of the original value of the key.
