Ok, I need to know how to display files like with ls -l except I only want to display files with no file extension. Anybody have any ideas?

These commands are essential when you're working with files and directories.

UNIX people will recognize that as output from a directory listing being redirected to a file, in this case, named "file". I'd like to create a list of my mp3s, and at 1500+, I'm not doing it by hand.
