Oh,
Code:
-n

is for numeric values. So would it just be
Code:
sort | who

And yes I can use Putty to connect to the school server, but only myself and the server admin are usually on, so not sure if it is really working to be honest (his name just might pop up first by default).

EDIT: I tried this and it did not work, because I did a reverse order sort using
Code:
who | sort -r

and my name came first, so that works. So my answer would thus be
Code:
who | sort

. I am not really sure why this order of who and sort works. Is it because you need to run who first so the sort takes the input from the other command (who)?

P.S. I am doing a small grading program for this same lab as well. I will post my results later tonight. Didn't post here because I had not yet tried anything. Should I open a new thread or post here?

RUPTIME(1)						    BSD General Commands Manual 						RUPTIME(1)

NAME
ruptime -- show host status of local machines SYNOPSIS
ruptime [-alrtu] [host ...] DESCRIPTION
The ruptime utility gives a status line like uptime(1) for each machine on the local network; these are formed from packets broadcast by each host on the network once every three minutes. If no operands are given, ruptime displays uptime status for all machines; otherwise only those hosts specified on the command line are dis- played. If hosts are specified on the command line, the sort order is equivalent to the order hosts were specified on the command line. Machines for which no status report has been received for 11 minutes are shown as being down, and machines for which no status report has been received for 4 days are not shown in the list at all. The options are as follows: -a Include all users. By default, if a user has not typed to the system for an hour or more, then the user will be omitted from the output. -l Sort by load average. -r Reverse the sort order. -t Sort by uptime. -u Sort by number of users. The default listing is sorted by host name. FILES
/var/rwho/whod.* data files SEE ALSO
rwho(1), uptime(1), rwhod(8) HISTORY
A ruptime utility appeared in 4.2BSD. BSD
March 1, 2003 BSD
