Here are four quick and easy ways to find out what version of Redis you’re using.

Option 1: The INFO Command

If you’re already connected to Redis, you can use the INFO command to return the Redis version:

INFO server

Example result:

# Server
redis_version:6.2.6
redis_git_sha1:00000000
redis_git_dirty:0
redis_build_id:c6f3693d1aced7d9
redis_mode:standalone
os:Darwin 21.5.0 arm64
arch_bits:64
multiplexing_api:kqueue
atomicvar_api:c11-builtin
gcc_version:4.2.1
process_id:29680
process_supervised:no
run_id:421213b8bcec62a47f96c073e6ce1c4450946a8a
tcp_port:6379
server_time_usec:1655300672629833
uptime_in_seconds:474326
uptime_in_days:5
hz:10
configured_hz:10
lru_clock:11133504
executable:/opt/homebrew/opt/redis/bin/redis-server
config_file:/opt/homebrew/etc/redis.conf
io_threads_active:0

The Redis version is on the second line.

It’s also possible to run the INFO command without any arguments, like this:

INFO

That returns a lot more information, such as info about the server, client connections, memory consumption, statistics, and more.

Option 2: redis-server --version

Another way to check the Redis version is with the --version option of the redis-server executable.

With this option, you run it from the command line – not from within Redis.

So, open a new command line and enter the following:

redis-server --version

Example result:

Redis server v=6.2.6 sha=00000000:0 malloc=libc bits=64 build=c6f3693d1aced7d9

You can alternatively replace --version with -v:

redis-server -v

Result:

Redis server v=6.2.6 sha=00000000:0 malloc=libc bits=64 build=c6f3693d1aced7d9

We can also use the Unix cut command to narrow it down to just the version number:

redis-server -v | cut -d= -f2 | cut -d ' ' -f1

Result:

6.2.6

We can even go a step further and remove the patch-level version if we want:

redis-server -v | cut -d= -f2 | cut -d ' ' -f1 | cut -d. -f-2

Result:

6.2

Option 3: redis-cli INFO server

Another way to do it from the command line is with the redis-cli terminal program. We can use this program to run a Redis command and receive its reply as standard output to the terminal.

Therefore, we can make use of the INFO server command like we did with the first option.

But with this option, we can use grep to extract just the line that contains the Redis version:

redis-cli INFO server | grep ^redis_version:

Result:

redis_version:6.2.6

We can also use the Unix cut command to remove the label if required:

redis-cli INFO server | grep ^redis_version: | cut -d: -f2

Result:

6.2.6

And we can expand it further to exclude the patch-level version:

redis-cli INFO server | grep ^redis_version: | cut -d: -f2 | cut -d. -f-2

Result:

6.2

Option 4: Start Redis in Standalone Mode

If you’re running Redis in standalone mode, you should be able to find the Redis version with a quick glance.

To run Redis in standalone mode, run the redis-server executable from the command line.

Here’s what happens when I start Redis in standalone mode on my Mac:

redis-server

Result:
