I wrote a small script that takes a filename from the command line argument, reads in the file, does some stuff and produces some output. It works and I'm reasonably happy with it. Now I'd like to make the script smarter about handling command line arguments.
So what I'd like to do is something like this: If ARGV[0] == nil puts "you need to specify a filename" exit end if ! File.exists?( ARGV[0] ) puts "Input file is incorrect or cannot be found." exit end Question: Is this the right way to do this sort of thing? I'm new to working with arguments. I read up on the "exit" command but I didn't really follow all of the thread explanation. Please let me know. Thanks.
