38 TEST IDENTIFIER : kill02 Sending a signal to processes with the same process group ID.
50 1. Sending a signal to pid of zero sends to all processes whose process
53 2. Sending a signal to pid of zero does not send to processes in another process group.
58 kiltcs02 1 PASS The signal was sent to all processes in the process group.
59 kiltcs02 2 PASS The signal was not sent to selective processes that were not in the process group.
62 kiltcs02 1 FAIL The signal was not sent to all processes in the process group.
63 kiltcs02 2 FAIL The signal was sent to a process that was not in the process group.
