Did you ever run the find command as Bill had suggested? I'm curious if you have another program called who that is in the users pathway before it hits the system who command that root runs.
example: [geo...@alpha LOGIN]$ echo $PATH /usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/usr/uv:/usr/uv/bin [geo...@alpha LOGIN]$ su - [r...@alpha root]# echo $PATH /bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/usr/bin/X11:/usr/X 11R6/bin:/usr/uv:/usr/uv/bin:/root/bin If there was a who command in /usr/local/bin, non root users would wind up running it whereas root users would run the normal who in /usr/bin Another longshot.... > -----Original Message----- > From: u2-users-boun...@listserver.u2ug.org > [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Brutzman, > Bill > Sent: Tuesday, January 19, 2010 8:33 AM > To: U2 Users List > Subject: Re: [U2] HP Unix "who am i" > > # find . -name who > ./usr/bin/who > > #cd /usr/bin > #ll who > -r-xr-xr-x 1 bin bin 82364 Sep 4 2003 who > # > _______________________________________________ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
