Only that I realized latter the intention of this construction. My previous suggestion was to use this construction on its own without "test": if echo "$MILTERSOCKET" | grep -q -v "^inet"; then ... fi (the return code is set by grep) This works too but there is an extra test for the empty string: if [ "$(echo $MILTERSOCKET | grep -v ^inet)" ]; then ... fi (the return code is set by 'test') Thanks -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
