Here are two quick and easy options to find out what version of the Redis client (redis-cli) you’re using.

Option 1: The HELP Command

If you’re already using redis-cli, you can run the HELP command to see what version it is:

HELP

Example result:

redis-cli 6.2.6
To get help about Redis commands type:
      "help @<group>" to get a list of commands in <group>
      "help <command>" for help on <command>
      "help <tab>" to get a list of possible help topics
      "quit" to exit

To set redis-cli preferences:
      ":set hints" enable online hints
      ":set nohints" disable online hints
Set your preferences in ~/.redisclirc

The redis-cli version is on the first line.

Option 2: Run redis-cli --version

If you’re not already using redis-cli, open a new command line and enter this:

redis-cli --version

Example result:

redis-cli 6.2.6

Alternatively, you can use the -v option (which is short for --version):

redis-cli -v

Result:

redis-cli 6.2.6

You can also incorporate the Unix cut command to remove the label if you’re so inclined:

redis-cli -v | cut -d ' ' -f2

Result:

6.2.6

And to remove the patch-level version:

redis-cli -v | cut -d ' ' -f2 | cut -d. -f-2

Result:

6.2
