You'd be better off using "ps auxc" here (that is, print only argv[0]): $ ps aux|grep aux df 642 0,0 0,4 648 444 p1 R+ 8:49 0:00,00 grep aux (sh) df 641 0,0 0,3 516 392 p1 R+ 8:49 0:00,00 ps aux <which is obviously wrong for your situation, since the "aux" `daemon' is not running> $ ps auxc|grep auxc <nothing, which is right> $ And even a better solution would be to pipe the ps output to a [your favorite scripting language] script to take only the name part of the output (to avoid clash with usernames/etc.). > > > -- > Alex > > Articles based on solutions that I use: > http://www.kruijff.org/alex/index.php?dir=docs/FreeBSD/ > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" > -- DoubleF There is a Massachusetts law requiring all dogs to have their hind legs tied during the month of April. --Signature=_Mon__24_Nov_2003_09_02_29_+0300_mfiw+0I+BfNMh0kR Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (FreeBSD) iD8DBQE/wZ8Awo7hT/9lVdwRAlTmAJ9CET4VeM8glKLvaKflanLaSPFEAACeOeEZ 36TdXJ0/x5ke7yPZMxOCSj0= =5/Av -----END PGP SIGNATURE----- --Signature=_Mon__24_Nov_2003_09_02_29_+0300_mfiw+0I+BfNMh0kR--
