There are a few problems in the script.

Quote:
${HOME}/${PROCESS}.pl ${OPTIONAL} 2>&1 > $LOGFILENAME &
#check exit status
status=$?
The value of $status is not the exit status of the Perl program, it is the exit status of "&" which would normally be zero. This affects the whole logic of your script.
Backgrounding the Perl program seems pointless because it is immediately brought to foreground.

Quote:
trap 'cleanup' 2 9 15 17 19 20
To be effective the trap needs to be before the "while" line.


The script as it stands will try to start an infinite number of identical Perl programs unless the trap is triggered when it will execute "cleanup" and leave the Perl program(s) running. If the value of $SLEEP} is greater than the run time of one Perl program it may only run one Perl program at a time.

There is no provision for stopping the Perl program or waiting for it to finish before starting another one. It is unclear whether you want to stop the Perl program when someone presses ctrl/c or ctrl/z . Maybe I'm being thick but I don't understand what you are trying to do.

SOAPSH(1p)						User Contributed Perl Documentation						SOAPSH(1p)

NAME
SOAPsh - Interactive shell for SOAP calls SYNOPSIS
perl SOAPsh http://services.soaplite.com/examples.cgi http://www.soaplite.com/My/Examples > getStateName(2) > getStateNames(1,2,3,7) > getStateList([1,9]) > getStateStruct({a=>1, b=>24}) > Ctrl-D (Ctrl-Z on Windows) or # all parameters after uri will be executed as methods perl SOAPsh http://soap.4s4c.com/ssss4c/soap.asp http://simon.fell.com/calc doubler([10,20,30]) > Ctrl-D (Ctrl-Z on Windows) DESCRIPTION
SOAPsh is a shell for making SOAP calls. It takes two parameters: mandatory endpoint and optional uri (actually it will tell you about it if you try to run it). Additional commands can follow. After that you'll be able to run any methods of SOAP::Lite, like autotype, readable, encoding, etc. You can run it the same way as you do it in your Perl script. You'll see output from method, result of SOAP call, detailed info on SOAP faulure or transport error. For full list of available methods see documentation for SOAP::Lite. Along with methods of SOAP::Lite you'll be able (and that's much more interesting) run any SOAP methods you know about on remote server and see processed results. You can even switch on debugging (with call something like: "on_debug(sub{print@_})") and see SOAP code with headers sent and received. COPYRIGHT
