That's a very informative link -- I can see how that might be helpful context for a new user. It's hard for me to get into that mental frame, since my first text editor was edlin for DOS. I'll stick by my recommendation to type first and study later, however. Experience is a powerful teacher.

Thank you for that link. I appreciate that he chose to intersperse the history of commands (such as grep!) within his explanation.

That was enlightening. Thanks for sharing!
