ObU*xNewbieHack: One of our university labs has a whole lot of SPARCs which my friends and I (all new to SunOS) would log on to; we wanted to check if anyone we knew was on at the same time (BIG lab, also dialin), so I wrote a csh script to finger all the machines and grep the output with a personal .people file (with friends' login names) and print a nawk-formatted report. It turned out a bit slow (30 machines to finger), so I got each finger to run in the background, putting it's output in a separate file; these were then cocatenated after a few seconds (still-running fingers were killed with a nawk script parsing ps -fu) and the formatting was done the old way. MUCH faster... a logical later step was adding external servers to finger (outside the local network). NOTE: This screws up other processing on a slow machine (upto 30 processes!).
