The `CONFIG GET` command is used to read the configuration parameters of a
running Redis server.
Not all the configuration parameters are supported in Redis 2.4, while Redis 2.6
can read the whole configuration of a server using this command.

The symmetric command used to alter the configuration at run time is `CONFIG
SET`.

`CONFIG GET` takes multiple arguments, which are glob-style patterns.
Any configuration parameter matching any of the patterns are reported as a list
of key-value pairs.

You can obtain a list of all the supported configuration parameters by typing
`CONFIG GET *` in an open `redis-cli` prompt.

All the supported parameters have the same meaning of the equivalent
configuration parameter used in the [redis.conf](https://redis.io/docs/latest/operate/oss_and_stack/management/config) file. The provided link has links to the `redis.conf` files for Redis version 6.2 and greater. See the [Redis souce code repo](https://github.com/redis/redis) for earlier versions.
