Even though we have finished almost all of the commands, there are several commands that most of us have only used a few times and don't really know very well. So, I think it would be fun to make a game out of having people guess a command simply based on a few clues. This would test people's knowledge of the commands, and subsequently help them more fully learn the commands.
Once somebody has correctly guessed a command, that person can pick a new command. When posting a command challenge, please don't provide any obvious hints or other clues that will easily give the command away. For example, if you choose to use a simple command for your challenge, try to come up with some little known properties of the command or state the properties so that they are kind of ambiguous.
EDIT: I decided it's kind of wasteful to start a new topic for each command, when we can just use this topic. So, I deleted the other topic, and reposted the first command challenge here. I'm still waiting, though, for somebody to try and guess it.
