[sf-perl] simultaneous processes?

[Garth Webb]

I think I'm lost on what you're trying to do; if its not too lengthy, can
you post exactly the script you're trying to run with the environment
variables (e.g. $file) explicitly defined?

If you're really doing a "perl -e" just to run system, you might consider
making this a shell script instead of a perl script.
