Thanks, > > Chris Simple: /dev/snd/* and /dev/dsp are device nodes - read special "files" that are used to communicate with the kernel. However, /usr/bin/vlc is binary.

On more thing, in-order to trash the vlc binary you had to run as root. I'd advise against using the root account to anything besides administration tasks. - Gilboa -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
