it clears the screen and gives me the output of w (you know, who's logged
in and what are they doing) and then it refreshes the display every 2
seconds (by default, you can change it to whatever you like)
9:31PM up 4 days, 10:26, 3 users, load averages: 0.13, 0.39, 0.44

andrew p1 eric 9:29PM 0 (pine)
andrew p2 eric 9:31PM 0 w
here's the man page if you're interested. I don't think we have anything
like it yet. I might have to try and do it myself.

WATCH(1) BSD Reference Manual WATCH(1)
NAME
watch - watch a program with update intervals
SYNOPSIS
watch [-n seconds] program [args ...]
DESCRIPTION
watch is a curses(3) based program that allows you to watch a program
as it changes. By default, it updates itself every 2 seconds. You can
specify the number of seconds with the -n option. The curses
package allows for quick updating of the screen through cursor optimization. The
program will end with a keyboard interrupt, which will leave the screen
in a valid yet cleared state.
EXAMPLE
watch -n 1 ps u
