Hmm, I'm afraid I don't know why that happens when setsid is invoked from a script. This returns immediately: $ setsid sleep 10 As does this: $ bash -c 'setsid sleep 10' But this doesn't: $ echo 'setsid sleep 10' > sleep.sh; bash sleep.sh Andy -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
