This traces signals sent via the kill() syscall. For example: # ./killsnoop TIME PID COMM SIG TPID RESULT 12:10:51 13967 bash 9 13885 0 12:11:34 13967 bash 9 1024 -3 12:11:41 815 systemd-udevd 15 14076 0 The first line showed a SIGKILL (9) sent from PID 13967 (a bash shell) to PID 13885. The result, 0, means success. The second line showed the same signal sent, this time resulting in a -3 (ESRCH: no such process). USAGE message: # ./killsnoop -h usage: killsnoop [-h] [-x] [-p PID] Trace signals issued by the kill() syscall optional arguments: -h, --help show this help message and exit -x, --failed only show failed kill syscalls -p PID, --pid PID trace this PID only examples: ./killsnoop # trace all kill() signals ./killsnoop -x # only show failed kills ./killsnoop -p 181 # only trace PID 181 |
