Redis String

Redis strings commands are used to manage string values in Redis. See the syntax for using Redis string commands.

Syntax:

Example

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

Here, SET and GET are commands and "javatpoint" is key.

Redis Strings Commands

Following is a list of some basic commands which are used to manage strings in Redis.

Index	Command	Description
1	SET key value	This command is used to set the value at the specified key.
2	GET key	This command is used to retrieve the value of a key.
3	GETRANGE key start end	This command is used to get a substring of the string stored at a key.
4	GETSET key value	This command is used to set the string value of a key and return its old value.
5	GETBIT key offset	This command is used to return the bit value at the offset in the string value stored at the key.
6	MGET key1 [key2..]	This command is used to get the values of all the given keys
7	SETBIT key offset value	This command is used to set or clear the bit at the offset in the string value stored at the key
8	SETEX key seconds value	This command is used to set the value with the expiry of a key
9	SETNX key value	This command is used to set the value of a key, only if the key does not exist
10	SETRANGE key offset value	This command is used to overwrite the part of a string at the key starting at the specified offset
11	STRLEN key	This command is used to retrieve the length of the value stored in a key
12	MSET key value [key value ...]	This command is used to set multiple keys to multiple values
13	MSETNX key value [key value ...]	This command is used to set multiple keys to multiple values, only if none of the keys exist
14	PSETEX key milliseconds value	This command is used to set the value and expiration in milliseconds of a key
15	INCR key	This command is used to increment the integer value of a key by one
16	INCRBY key increment	This command is used to increment the integer value of a key by the given amount
17	INCRBYFLOAT key increment	This command is used to increment the float value of a key by the given amount
18	DECR key	This command is used to decrement the integer value of a key by one
19	DECRBY key decrement	This command is used to decrement the integer value of a key by the given number
20	APPEND key value	This command is used to append a value to a key
