   This is slide, a little program I find very handy on the 3b1.  It allows

You worked much too hard at that.

main (argc, argv)
int argc;
char *argv[];
{
	char *shell = getenv("SHELL");
	setuid (0);
	setgid (0);
	execv ((shell ? shell : "/bin/csh"), argv);
}

This has the effect that calling this program (we call it "enable") isz
done just as one would call a shell, e.g., "enable -fc 'chown username
/File/Name'" does what you expect.

Make it mode 04750, chown'd to root, and hide it in a directory of
mode 0700 which is owned by a user who is allowed to use it.

And then kill that user if he ever walks away from his terminal while
logged in.

Half :-).
