`<>` is a file descriptor reading operation and it is already inside the script, so you should run either `perl script.pl mytext.txt >output.txt` (passing filename as command line argument) or `perl script.pl <mytext.txt >output.txt` (passing file contents as STDIN). Sorry if my advice was wrong.	[reply] [d/l] [select]
