Hi, Wow. Lots of feedback. REALLY GOOD FEEDBACK!
This was my first question to this list. Let me clarify my question. I want to use tst.py as follows: tst.py input-file output-file OR cat data-file | tst.py - output-file OR cat data-file | tst.py output-file tst.py input-file output-file works well tst.py - output-file works well The question boils down to "tst.py output-file"... which is a "parsing the args" question which you "guys" have caused me to think more clearly about. If there's just 1 arg, consider it an output-file and read from stdin and write to output-file ONLY if output-file does not exist. Thank you all for your very helpful and informative responses.
