Thanks a lot again.
Hi newbie_01,
I'm glad it is working for you.
Unfortunately,
kill -9 can't be caught so a
trap won't work in that case. Fortunately, that is the only case that won't work. You can use
trap to clean up on normal exit, SIGINT (
kill -2 or ctl-
c), and SIGQUIT (
kill -3 or ctl-
\). The SIGINT and SIGQUIT cases are significant since they have keyboard shortcuts as well as
kill commands that can be used to generate them. The control
C and control
\ are the usual defaults on American keyboards, but you can change the characters used to generate both of those signals using the
stty utility if you want different keyboard shortcuts.
If you use SIGKILL (
kill -9) to terminate a job (any job), you'll have to manually go in and delete any temporary files that job may have created. Always try using SIGINT first to gives jobs a chance to clean up after themselves and use SIGKILL only as a last resort.

KILL(1) General Commands Manual KILL(1)
NAME
kill, broke - print commands to kill processes
SYNOPSIS
kill name
broke
DESCRIPTION
Kill prints commands that will cause all processes called name and owned by the current user to be terminated. Use the send command of
81/2(1), or pipe the output of kill into rc(1) to execute the commands.
Kill suggests sending a kill note to the process; the same message delivered to the process's ctl file (see proc(3)) is a surer, if heavy
handed, kill, but is necessary if the offending process is ignoring notes.
Broke prints commands that will cause all processes in the Broken state and owned by the current user to go away. When a process dies
because of an error caught by the system, it may linger in the Broken state to allow examination with a debugger. Executing the commands
printed by broke lets the system reclaim the resources used by the broken processes.
