Redis version number view command details

The commands that can view the Redis version number are: INFO INFO serverECHO ECHO versionCLIENT LIST and calculate the connected_since value (only applicable to running Redis servers)

Redis version number view command details

To view Redis version number, the most commonly used command is INFO .

1. INFO

The INFO command is a general information command that can obtain various Redis information by specifying different parameters. Among them, info server parameter can obtain server information, including the Redis version number.

Command format:

 <code>INFO server</code>

Return the result example:

 <code>redis_version:7.0.4</code>

2. ECHO

The ECHO command is a simple string echo command. However, in Redis 2.6 and later, it also supports extended functionality to get server information. To get the Redis version number, you can use the following command:

Command format:

 <code>ECHO version</code>

Return the result example:

 <code>"redis_version:7.0.4"</code>

3. CLIENT LIST

<code>CLIENT LIST</code> command lists all client information connected to Redis. Among them, the connected_since field records the client connection time and can be converted to a timestamp to calculate the Redis server startup time.

Command format:

 <code>CLIENT LIST</code>

Return the result example:

 <code>id=1 addr=127.0.0.1:6379 connected_since=1654590152454</code>

Redis server startup timestamp = connected_since value - client connection time difference

Note: This method is only applicable to running Redis servers. If Redis just started, the connected_since field may be empty.
