Redis string data type for managing the commands redis string value, the basic syntax is as follows:
grammar
redis 127.0.0.1:6379> COMMAND KEY_NAME
Examples
redis 127.0.0.1:6379> SET coderctokey redis
OK
redis 127.0.0.1:6379> GET coderctokey
"redis"
In the above example we used the GET and SET commands, key to coderctokey.
Redis string command
The following table lists common redis command string:
Number and description of command
1SET key value
Setting the value of the specified key
2GET key
Gets the value of the specified key.
3GETRANGE key start end
Returns string key value substring
4GETSET key value
Set the value of a given key value, and returns the key of the old value (old value).
5GETBIT key offset
Key string stored value, obtaining bits (bit) on the specified offset.
6MGET key1 [key2..]
Get all (one or more) of values of the given key.
7SETBIT key offset value
String stored key value, set or clear the bits (bit) on the specified offset.
8SETEX key seconds value
The value associated with the value key, and the key seconds The expiration time is set (in seconds).
9SETNX key value
Only settings key in the key does not exist.
10SETRANGE key offset value
Cover addressed by the value parameter values given string stored key, offset offset from the start.
11STRLEN key
Returns the length of the string stored key value.
12MSET key value [key value ...]
Simultaneously providing one or more key-value pair.
13MSETNX key value [key value ...]
Simultaneously providing one or more key-value pairs, if and only if all the given key does not exist.
14PSETEX key milliseconds value
This command and SETEX command similar, but it is set in milliseconds survival key is, rather than as SETEX command, in seconds.
15INCR key
The key stored in a digital value incremented by one.
16INCRBY key increment
The key the stored value plus a given incremental value (increment).
17INCRBYFLOAT key increment
The key stored in a floating-point value plus the increment value given (increment).
18DECR key
The key stored digital value minus one.
19DECRBY key decrement
key value stored by the given decrement value (decrement).
20APPEND key value
If the key already exists and is a character string, APPEND command specified key value appended to the original value (value) of.
