...you learn 'awk' just so you can create this:
hostinfo -ALL -LINUX | awk '/0.00/ {i=1;while(match(substr($1,i++,1),"[a-z0-9]"));print "ssh -f", substr($1,1,i-2), "run.sh", 4038400+j*200, " ", 4038600+(j++)*200}' | csh
The first command dumps the names and load info of all the linux machines connected to the university's network.
The second parse out the hostname of each computer with a load of 0.00 and prints a special ssh command (-f is evil, read the manpage).
The third piece is just the shell it dumps all the commands to.
Just change the range, run it on a shell, enter my password a few dozen times, and I've enslaved an army of P4s to factor for the evening.
Anyone else do goofy things to get extra cpu cycles?
