If you want to know how to do something in UNIX, you need to know exactly one command before you start: "man".

This lets you look up how things work in the UNIX manual pages. If you look up the "man" commmand, you'll see that if you use the -k option, you can do a keyword search on any topic you want.

Let's find out what commands might be involved in clearing the screen, shall we?

%man -k clear | grep screen clear(1) - clear terminal screen

Right: there's exactly one command, called "clear", which clears the screen.

See? If people read the UNIX FAQ, they won't need to read your little FAQ. If they're not the type to read a FAQ, writing one won't help.

If they do read the UNIX FAQ, they'll also know how to look up the man page for perl. The man page for perl points out that there is a man page for the Perl FAQ.

The Perl FAQ explictly lists the answer to the question: "How do I clear the screen".

We don't need another FAQ: we need people to read the FAQs that already exist.
