Sorry if I'm confused about how to script this. The following (bash syntax) is a better example: grep -q foo <(sh -c 'printf foo ; sleep 30' &) This blocks 30 seconds before exiting. In contrast, grep -q foo <(sh -c echo foo ; sleep 30' &) (only difference is the newline at the end of the line) does exit immediately. Regards, /Niels -- Niels Möller.
