That looks overly convoluted to me. What about this (untested, but shell syntax works):
if [ -e "/tmp/.X${X2GO_PORT}-lock" ] || [ -e "/tmp/.X11-unix/X${X2GO_PORT}" ] || netstat -ntl 2>/dev/null | grep -q ":${X2GO_PORT}"; then OUTPUT="XXX" else SESSION_NAME=${USER}-${X2GO_PORT}-`date +"%s"` fi
Cheers, Reinhard
What if X2GO_PORT is 6051 and for some reason there is a service listening on port 60513? Won't it erroneously match? - John
