I don't know how to do this, but I did notice this much: (the binary does remain accessible even after it's removed, as long as it doesn't exit). #include <sys/types.h> #include <stdio.h> #include <stdlib.h> #include <unistd.h> int main(int argc, char **argv) { int id; char cmd[128]; unlink(argv[0]); id = getpid(); printf("pid == %d\n", id); sprintf(cmd, "ls -l /proc/%d", id); system(cmd); exit(0); } $ cc foo.c $ ./a.out pid == 78597 total 4 -r--r--r-- 1 zach wheel 0 Apr 23 07:00 cmdline --w------- 1 zach wheel 0 Apr 23 07:00 ctl -r--r--r-- 1 zach wheel 76 Apr 23 07:00 etype -rwxrwxr-x 0 zach wheel 3637 Apr 23 07:00 file -rw------- 1 zach wheel 176 Apr 23 07:00 fpregs -r--r--r-- 1 zach wheel 76 Apr 23 07:00 map -rw-r----- 1 zach kmem 0 Apr 23 07:00 mem --w------- 1 zach wheel 0 Apr 23 07:00 note --w------- 1 zach wheel 0 Apr 23 07:00 notepg -rw------- 1 zach wheel 76 Apr 23 07:00 regs -r--r--r-- 1 zach wheel 0 Apr 23 07:00 status $ [note the '0' links for the binary] -- Zach Heilig <z...@uffdaonline.net> To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-current" in the body of the message
