You can get around this using perl's -i switch: perl -pi -e 's/shutdown -t1 -a -r now/shutdown -t1 -a -h now/' /etc/inittab telinit q (Or -i.pre-lenny-shutdown if you want to keep a backup as above.) -- Colin Watson [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
