GNU FindUtils provides a small suite of commands which helps you locate specific files (though Grep's, which I'll cover after AWK, developed seperately). I think I'll categorize these as reencoding the filesystem into something more concise.
The `find` command, which I'll cover today, lists all descendant filepaths under a directory (defaulting to ".") so that they can be `grep`ed. GNU FindUtils also provides other arguably more optimal commands for the same thing, but `find`'s still useful.
