yeah, check it out, its a little script for lauching quake3 (urban terror 
mod).  i got a bunch of computers behind a linksys router, so each user has 
to have a unique net_port.

SUFFIX=$(($UID % 100))
if [ "$SUFFIX" -lt 10 ] ; then
	NETPORT=2790${SUFFIX}
else
	NETPORT=279${SUFFIX}
fi
echo "Starting Urban Terror on netport ${NETPORT}."
if [ -n "$DISPLAY" ] ; then
	/shared/games/quake3/quake3 +set fs_game q3ut2 +set net_port ${NETPORT}
else
	startx -e /shared/games/quake3/quake3 +set fs_game q3ut2 +set net_port 
${NETPORT}
fi


linux is so cool, i would have no idea how to do something like this in win32.

thanks for the tips (David and Gordon), the script works great now.
