Redis second (redis basic command)

- x reading a parameter from standard input

such as:

Echo–en "Shaw" |. /redis-cli–x SetName = = Set name Shaw

- R repeats the number of times a command is specified

- I. set the interval for command execution

such as:

12345

[[email protected]_Redis1 src]# ./redis-cli -r 100 -i 1 info | grep total_commands_processed      # 每隔1秒执行一次，共执行100次info命令total_commands_processed:140total_commands_processed:141total_commands_processed:142total_commands_processed:143

--rdb gets the specified Redis instance of Rdb file, save to local

For example:

123	[[email protected]_Redis1 src]# ./redis-cli --rdb /home/tools/6379.rdbSYNC sent to master, writing 31 bytes to ‘/home/tools/6379.rdb‘Transfer finished with success.

--scan Use Scan Command Scan lists Redis in the Key

--pattern Specifies the scanned Key of the pattern, compared to keys Pattern mode, does not block for a long time Redis while the command requests from other clients remain blocked

For example:

12	[[email protected]_Redis1 src]# ./redis-cli --scan --pattern ‘na*‘name

- H Specifies the linked IP

- P Specify the connection port

-A Specify the password for the connected user, or you can connect Auth Command Complete Authorization

- S only the client and the server are on the same machine and can be UNIX Sockets Way to connect

--stat Get Redis the diagnostic data

For example :

1234567

[[email protected]_Redis1 src]# ./redis-cli --stat------- data ------ --------------------- load -------------------- - child -keys       mem      clients blocked requests            connections          1          1.78M    1       0       169 (+0)            22          1          1.78M    1       0       170 (+1)            22          1          1.78M    1       0       171 (+1)            22          1          1.78M    1       0       172 (+1)            22

--pipe Send the original Redis Protocl format data to server-side Execution

--bigkeys the Redis in the Key sampling to find the larger Keys, You can also get approximate data statistics based on sampling.

For example :

12345678910111213141516

[[email protected]_Redis1 src]# ./redis-cli --bigkeys# Scanning the entire keyspace to find biggest keys as well as# average sizes per key type.  You can use -i 0.1 to sleep 0.1 sec# per 100 SCAN commands (not usually needed).[00.00%] Biggest string found so far ‘name‘ with 4 bytes-------- summary -------Sampled 1 keys in the keyspace!Total key length in bytes is 4 (avg len 4.00)Biggest string found ‘name‘ has 4 bytes1 strings with 4 bytes (100.00% of keys, avg size 4.00)0 lists with 0 items (00.00% of keys, avg size 0.00)0 sets with 0 members (00.00% of keys, avg size 0.00)0 hashs with 0 fields (00.00% of keys, avg size 0.00)0 zsets with 0 members (00.00% of keys, avg size 0.00)

--latency gets the request time to the command, including (MIN,MAX,AVG)
