If you type the following commands at the shell command prompt (bash or ash) : sh -c "sleep 10 &" ps you will see a process whose PPID and PGID are 0. I really do suppose it was not meant to allow such a thing. Normally, a detached process should have ppid and pgid with value 1. That's what does occur when you type the following commands : sleep 10 & ps Best Regards, ===== Robert Legros south Brussels, Belgium robert_legros AT yahoo DOT com __________________________________________________ Do You Yahoo!?
