Where is the FLUSHALL command in http://try.redis.io/?

Question

I am learning Redis right now and one of the first things I did was trying to interactively issue commands to an online Redis server: http://try.redis.io/

The FLUSHALL command is well documented here: http://redis.io/commands/flushall and is also referenced in this SO answer.

But when I try to issue it, it is simply not recognized:

My question: Why? Where has it disappeared? After all, the documentation says it is:

"Available since 1.0.0."

Answer 1

The web interface at try.redis.io, while executing against a real Redis database, offers only a subset of the actual commands. Because the database is shared by all users of the interface, some commands (FLUSHALL for example) are disabled in it.
