No, this is not true. You cannot intercept a kill -s SIGKILL. SIGKILL
is signal 9.
However, you easily can intercept a SIGTERM. Try this small C snippet,
and a kill <pid> won't do any harm to the process.
#include <stdio.h>
#include <stdlib.h>
#include <signal.h>
#include <unistd.h>
int main() {
signal(SIGTERM, SIG_IGN); // SIG_IGN = ignore the signal
sleep(120);
exit(0);
}
