The script you post is terrifying, but I follow the basic reasoning. I would recommend that nobody runs that script on an operational system - especially one which has data.

Sorry, but it is scripts such as this which issue "kill -9" arbitarily actually cause the situation which we see with "who -d" in the original post.

If you were forced to issue a kill against orphan interractive process it should be "kill -15" or whatever "kill" signal is required by the application.

Never issue "kill -9" unless you are having trouble shutting a system down or encounter a process which is definitely stuck on impossible I/O.

KILL(1) 						    BSD General Commands Manual 						   KILL(1)

NAME
kill -- terminate or signal a process SYNOPSIS
kill [-s signal_name] pid ... kill -l [exit_status] kill -signal_name pid ... kill -signal_number pid ... DESCRIPTION
The kill utility sends a signal to the process(es) specified by the pid operand(s). Only the super-user may send signals to other users' processes. The options are as follows: -s signal_name A symbolic signal name specifying the signal to be sent instead of the default TERM. -l [exit_status] Display the name of the signal corresponding to exit_status. exit_status may be the exit status of a command killed by a signal (see the special sh(1) parameter '?') or a signal number. If no operand is given, display the names of all the signals. -signal_name A symbolic signal name specifying the signal to be sent instead of the default TERM. -signal_number A non-negative decimal integer, specifying the signal to be sent instead of the default TERM. The following pids have special meanings: -1 If superuser, broadcast the signal to all processes; otherwise broadcast to all processes belonging to the user. 0 Broadcast the signal to all processes in the current process group belonging to the user. Some of the more commonly used signals: 1 HUP (hang up) 2 INT (interrupt) 3 QUIT (quit) 6 ABRT (abort) 9 KILL (non-catchable, non-ignorable kill) 14 ALRM (alarm clock) 15 TERM (software termination signal) kill is a built-in to csh(1); it allows job specifiers of the form ``%...'' as arguments so process id's are not as often used as kill argu- ments. See csh(1) for details. SEE ALSO
csh(1), pgrep(1), pkill(1), ps(1), kill(2), sigaction(2), signal(7) STANDARDS
The kill function is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible. HISTORY
A kill command appeared in Version 6 AT&T UNIX. BSD
April 28, 1995 BSD
