Full Discussion: Script which uses “kill -9” command
Top Forums Shell Programming and Scripting Script which uses “kill -9” command Post 302445341 by agama on Sunday 15th of August 2010 11:47:38 AM

Off the top of my head, I'd say that tomcat is ignoring TERM (15) signals (the default when you only provide a PID to the kill command). This is why 'kill $PID' seems not to work. It is likely ignoring HUP (1) and QUIT (3) signals too.

Quote:
is there any other way to get rid of this.
I'm not really sure what this is that you are wanting to get rid of. The running process, the script, the need for kill -9?

I'll go on the assumption that you are wanting to cause a core dump which is not produced when using -9 (SIGKILL). Try using 'kill -6' (abort) -- I'd hope that the tomcat developers left this signal set to it's default value (terminate programme and generate a core dump).

kill

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 processes 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]
	     If no operand is given, list the signal names; otherwise, write the signal name corresponding to exit_status.

     -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.

     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)

     Some shells may provide a builtin kill command which is similar or identical to this utility.  Consult the builtin(1) manual page.

SEE ALSO

     builtin(1), csh(1), killall(1), ps(1), kill(2), sigaction(2)

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.

BUGS

     A replacement for the command ``kill 0'' for csh(1) users should be provided.
