That's the Unix Way (tm).

This is an important concept > which should not be hidden. I don't limit my remarks to "Said beginners", I think the option would be useful to practised Linux users too. But remembering the befuddlement, confusion and fluster I felt as a new user did bring the issue back to mind. Nor do I think it is the place of any Linux distribution to decide when and what users should learn. To me, that's M$ type of thinking. Perhaps some users can't remember as far back as when they first started using Linux or Unix, or perhaps they have always had an intuitive grasp of how computers work. Or, maybe, there is just the natural old pro desire to force an unnecessarily onerous initiation period on beginners. In lieu of providing an additional option to 'ls' coreutils could provide an 'lsf' command that would print the simple information that is desired. I didn't jump into this thread because it was something I REALLY NEEDED, but because I thought it might be useful to others. Such an lsf command should be a kind of a command line alternative to gui file browsers like nautilus. -- Regards Bill Fedora 11, Gnome 2.26.3 Evo.2.26.3, Emacs 23.1.1 -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
