Leave off the -u and you will get what you're looking for. The message you got is actually the man command telling you that -u isn't an option to man, and then giving you the syntax of the man command. You just type "man up2date" to view the manpage for up2date. Your question about what the -u option to up2date does will be answered therein. ~Jeff On Wednesday, October 23, 2002 9:48 AM, Michael Havens wrote: > Then I tried to find out what 'up2date -u' does but the man pages say: > > [bmike1@localhost bmike1]$ man up2date -u > man: invalid option -- u
