Redis string (String)

Redis string data type associated commands for managing redis string values, the basic syntax is as follows:

grammar 

redis 127.0.0.1:6379> COMMAND KEY_NAME

Examples 

redis 127.0.0.1:6379> SET w3bigkey redis
OK
redis 127.0.0.1:6379> GET w3bigkey
"redis"

In the example above, we use theSET and GETcommands, key to w3bigkey.

Redis string command

The following table lists the common redis command string:

No. Command and description
1 SET key value
Set the value of the specified key
2 GET key
Gets the value of the specified key.
3 GETRANGE key start end
Returns the value of the key sub-character string
4 GETSET key value
Given key value is set value, and returns the key of the old value (old value).
5 GETBIT key offset
String key value stored to get bit (bit) on the specified offset.
6 MGET key1 [key2 ..]
Get all (one or more) of the value of a given key.
7 SETBIT key offset value
String key value stored, set or clear bit (bit) on the specified offset.
8 SETEX key seconds value
The value of the value associated with the key, and the key expiration time set seconds (in seconds).
9 SETNX key value
Only set the value of key when key does not exist.
10 SETRANGE key offset value
Cover with a value written arguments given string key value stored, offset offset from the beginning.
11 STRLEN key
Returns the length of the string value key stored.
12 MSET key value [key value ...]
While providing one or more key-value pairs.
13 MSETNX key value [key value ...]
While providing one or more key-value pairs, if and only if all the given key does not exist.
14 PSETEX key milliseconds value
This command SETEX command similar, but it set in milliseconds key lifetime, rather than SETEX command, as in seconds.
15 INCR key
The key stored digital value is incremented by one.
16 INCRBY key increment
The key stored value plus a given increment (increment).
17 INCRBYFLOAT key increment
The key stored value plus the given floating-point increment (increment).
18 DECR key
The key stored digital value minus one.
19 DECRBY key decrement
key stored value minus the value given decrement (decrement).
20 APPEND key value
If the key already exists and is a string, APPEND command value is appended to the end of the key original value.
