Hmm, here I modeled Ndiff after GNU diff: $ diff diff: missing operand after `diff' diff: Try `diff --help' for more information. On the other hand, Nmap prints out usage information when run without arguments. I think I like it better when the error message is on its own in the output and not followed by non-error information; when there's a lot of information on the screen it's easy to miss the real error. It would look like $ ndiff ./ndiff: need exactly two input filenames. Usage: ./ndiff [option] FILE1 FILE2 Compare two Nmap XML files and display a list of their differences. Differences include host state changes, port state changes, and changes to service and OS detection. -h, --help display this help -v, --verbose also show hosts and ports that haven't changed. --text display output in text format (default) --xml display output in XML format I'm inclined to leave the output as it is, but I'm willing to hear other points of view.
