Print number of keys in Redis

Is there a way to print the number of keys in Redis?

I am aware of

keys *

But that seems slightly heavy weight. - Given that Redis is a key value store maybe this is the only way to do it. But I would still like to see something along the lines of

count keys *

You can issue the INFO command, which returns information and statistics about the server. See here for an example output.

As mentioned in the comments by mVChr, you can use info keyspace directly on the redis-cli.

redis> INFO

redis_git_sha1:00000000
redis_git_dirty:0

DBSIZE returns the number of keys and it's easier to parse.

Downside: if a key has expired it may still count.

The DBSIZE command returns the number of keys
