2.23.1.4. Redis-cli utility

For the utility to work, you must connect Redis in your hosting account.

The Redis-cli utility is a complete Redis client and is used to manipulate data stored in the Redis database.

View quick documentation:

redis-cli -h

A Unix socket is used to connect to Redis. The command to connect looks like this:

redis-cli -s ~/.system/redis.sock

Key -s must be specified, without it you cannot connect to a Unix socket.

After connecting to a Redis socket, the following popular commands are available for use:

Print all recorded keys:
```
keys '*'
```
Display all recorded keys that have in the name key_:
```
keys key_*
```
You can use symbols in the pattern:
- * — any number of any characters.
- ? — any one character.
Write data example_data with key key_example:
```
set key_example "example_data"
```
Retrieve data recorded earlier with a key key_example:
```
get key_example
```
Get the type of data stored in this key:
```
type key_example
```
Rename key from key_example on key_another_example:
```
rename key_example key_another_example
```
Check for the existence of a key:
```
exists key_example
```
If the key exists, it will output 1, if not - 0.
Delete data and key key_example:
```
del key_example
```
Get key lifetime:
```
ttl key_example
```
By default, the output is -1, which means there is no lifetime limitation.
Install TTL and the data written in it, after which the key will be deleted:
```
expire key_example
```

Activate the mode of writing commands to the queue:
```
multi
```
This mode is useful for executing multiple commands one at a time.
Execute all commands written to the queue after multi:
```
exec
```
If an error occurs while specifying commands, then all entries in the queue will be discarded.

Increment, increasing the value of the data by one, written in the key key_example:
```
incr key_example
```
Increment, increasing the data value by the number specified instead of increment:
```
incrby key_example increment
```
Decrement, decrement of the data value by one, written in the key key_example:
```
decr key_example
```
Decrement, increasing the data value by the number specified instead of decrement:
```
decrby key_example decrement
```

Append to the end of the key data string key_example text test_text:
```
append key_example "test_text"
```
Length of the written data string in the key:
```
strlen key_example
```
Get a specific character range of a string:
```
getrange key_example start end
```
The start and end of the range are specified instead of start and end... For example, for the line 1234567890 command getrange key_example 2 6 willreturn 4567... The characters are counted from 0.
Replace the data written in the key, starting with the character under the number start:
```
setrange key_example start "text"
```
For example, the line 1234567890 command setrange key_example 2 "123" will change to 1212367890.

Add a new element with text to the end of the list test:
```
rpush key_example "test"
```
List the elements of the list, starting with the element numbered start and ending with the number stop:
```
lrange key_example start stop
```
Get the number of items in a list:
```
llen key_example
```
Remove the first element of the list and get the data for the following:
```
lpop key_example
```

The commands are described in more detail in official documentation.
