in reply to System(), writing to a new file

I am not sure about this, but are you able to redirect the output?
system("sort somefile.txt >somefile2.txt") or die;
If I've remembered my unix syntax, the following will send any error messages (on STDERR) to the file "error.txt"
system("sort somefile.txt >somefile2.txt 2>error.txt") or die;
IIRC you must use the single argument version of system() for redirections to work. (I think the multiple argument versions bypass the shell.) I'd check this though!

    I saw there was no redirection in the OP's code. That's why I suggested redirection in my post.
    But I missed the sort filename > newfilename comment in the OP text.
