TKILL(1)                            LAM TOOLS                           TKILL(1)



NAME
       tkill - Terminate LAM on one node.

SYNOPSIS
       tkill [-dhvN] [-f killfile]

OPTIONS
       -d             Turn on debugging mode.  This implies -v.

       -h             Print the command help menu.

       -v             Be verbose.

       -N             Pretend; do not take action.

       -f killfile    Use killfile as the name of the kill file.

DESCRIPTION
       The tkill tool terminates the LAM session started by hboot(1) on the
       local node.  tkill makes use of a kill file created by the LAM kernel,
       which contains the process identifiers of every LAM process in ASCII
       format.  A SIGHUP (see signal(3)) signal is sent to every process listed
       in the kill file.  tkill waits a short period of time for each process to
       die.  By adding the debug option, the user can see the final disposition
       of each process.  The mission is accomplished if all processes end up
       dead.

       In LAM, the first process to be killed is always the kernel.  When the
       kernel receives its termination signal, it propagates the signal to all
       of its constituent processes.  Therefore, tkill will ordinarily be racing
       the kernel to kill all other processes.  This redundant aspect of tkill
       allows it to be used as a general purpose tool in association with
       hboot(1).

FILES
       /tmp/lam-$USER@hostname       the kill file, created by the kernel, where
                                     $USER is the userid, and hostname is the
                                     name of the local machine
