Any good OS X terminal commands tut for beginner?

Hey,

Some weeks ago, I've seen here a very promising and complete OS X terminal/shell tutorial but I haven't bookmarked it. Anyone has a link?

But you can search.

Of course I have asked to search engines... But they haven't found it... that's why I ask now for human memories.
