I have a difficult time with the following bash (or maybe cygwin.dll) behavior: bash-2.05a$> java com.edgility.<blah>.ClassName & bash-2.05a$> tail -f mylogfile ... ctrl-C as soon as I hit ctrl-C the java VM exits. In the bash reference manual it talks about background processes being in different process groups and not propagating a SIGINT to those processes. I read through every option available to stty and tried various ones that sounded related with no effect. I have also tried starting the VM with: (trap "" 1 2 3; java com.edgility.<blah>.Classname &) also with no effect. Further, I read a lot in the mail archive for this group about bash vs. cmd and the difference between ctrl-C and ctrl-break and how cygwin.dll handles interrupts. It looks like a change went into 1.3.7 controlling how signals are propagated, but I wasn't clear on exactly what effect the change had. I was running 1.3.6 and upgraded to 1.3.9 and the behavior is exactly the same in both cases for me. What is absolutely baffling is that a co-worker is also running 1.3.9 and the same version of bash and he does not see this behavior. All of this leaves me wondering, 1. what is supposed to happen to background processes in bash when one types the interrupt character? 2. is there some configuration option that affects this? Any insights (penetrating or otherwise) would be appreciated, jeff meredith (jmeredith AT edgility DOT com) -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
