Because the "kill" command is builtin to some shells (including bash and csh) and their versions of "kill" treat the "-l" flag differently. If you ran the external "/bin/kill -l" command the result would be the same regardless of the shell, but since these shells have their own "kill" function you're not running the /bin/kill program normally. -- Ben Smithurst / ben@FreeBSD.org [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (FreeBSD) Comment: For info see http://www.gnupg.org iD8DBQE7U1ApbPzJ+yzvRCwRAhGZAJoDGKQTGJWn/uUmiqiym7dPiGDkTQCgg0lC 7hskRDkauSaGUo8f44pv4oQ= =Norh -----END PGP SIGNATURE-----
