It would be really cool if shell lines included some sort of hyper-linking to man pages based on the grammar of each shell command and its arguments. Have one line that is the hyperlinked command, and another than has the command in a textfield. So rather than just a site of semi-magical incantations, it can be a catalyst for exploratory learning.<p>It is a little-pie-in-the-sky, I admit. The top command when I visited was `sudo`. What argument `sudo` takes depends upon the shell the user is using to execute `sudo`. Perhaps this could be a preference set somewhere, along with the OS being used. And maybe have a sister site where people contribute shell command grammars in some standardized syntax. I wonder how many people would be willing to provide those, though. Hmm.<p>This wasn't mentioned in the prior submission of this site, and it didn't occur to me until seeing it again. Just thinking out loud.
