Thanks for your reply. I'm still a little uncertain about performing any kind of operation on this returned value. I actually only want to determine if there is a processID, and if there is, kill it. (That part I have, using a | xargs kill.) If there isn't a process then just carry on doing whatever comes next in the script.
So I'm trying this:
if ( $processID > 0 ) then ...
but I get an error,
16305: not found
(where 16305 is the value of the variable).
What is it that's not being found?
Should I just make it simpler and compare $processID to null or ""?
Thanks.

kill.d(1m) USER COMMANDS kill.d(1m)
NAME
kill.d - snoop process signals as they occur. Uses DTrace.
SYNOPSIS
kill.d
DESCRIPTION
kill.d is a simple DTrace program to print details of process signals as they are sent, such as the PID source and destination, signal num-
ber and result.
This program can be used to determine which process is sending signals to which other process.
Since this uses DTrace, only users with root privileges can run this command.
EXAMPLES
Default output, print process signals as they are sent.
# kill.d
FIELDS
FROM source PID
COMMAND
source command name
TO destination PID
SIG destination signal ("9" for a kill -9)
RESULT result of signal (-1 is for failure)
DOCUMENTATION
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
bose descriptions explaining the output.
EXIT
kill.d will run forever until Ctrl-C is hit.
