rovf:

I think that the problem you're having is that the perl executable doesn't manage I/O redirection. Normally that's handled by the shell. So the command you're giving doesn't actually try to redirect STDOUT and STDERR--instead it's just passing ">out.txt" and "2>&1" as arguments to the myProg.pl script.

Why not simply add command-line options to myProg.pl to have alternate output streams? Then you don't have to detect redirection--you just tell myProg where to send the output.
