The general format for output is: name time where: =over =item name user's login name. =item time time since user's login. =back =head2 OPTIONS The following options are supported: =over 4 =item -b Indicate the approximate time and date of the last reboot. =item -B Indicate a more exact but slower to acquire time and date of the last +reboot. =item -H Output column headings above the regular output. =item -h Display syntax. =back =head1 EXAMPLE Below is an example of the output B<who> provides without options: C:\> who shoehorn unknown Administrator Jun 22 9:39 Below is an example of the output of B<who -H>: C:\> who -H USER LOGIN-TIME shoehorn unknown Administrator Jun 22 9:39 Below is an example of the output of B<who -b> and B<who -B>: C:\> who -b system boot Jun 21 15:29 =head1 ENVIRONMENT The working of B<who> is not influenced by any environment variables. =head1 BUGS B<who> isn't as nice as I would like, but Win32 isn't Unix, now is it? + This I<really> doesn't like Samba domain controllers, which is whi +I added the 'unknown' entry in the output. The B<-b> option returns an approximate uptime. It uses the Win32::Ge +tTickCount() function, an imprecise mechanism. A better was to derri +ve the last boot is to query the event log for the most recent 6005 o +r 6009 event and grab that time. If log files are large, this can be + time consuming. B<printf> does not seem to want to pad numbers with '0's. =head1 STANDARDS It does not make sense to talk about standards in a B<who> manual page +. =head1 REVISION HISTORY who Revision 1.0 2000/06/22 07:14:57 idnopheq Initial revision =head1 AUTHOR The Perl implementation of B<who> was written by Dexter Coffin, I<idno +pheq@home.com>. =head1 COPYRIGHT and LICENSE This program is copyright by Dexter Coffin 2000.
