| Shell Games |
If you've ever used a shell (UNIX or MS-DOS) before, you're probably already familiar with command-line options - they're the little arguments you pass to a program you're executing on the command line in order to modify its behaviour. For example, if you're deleting a directory, you could add a parameter to the command line to tell the system to delete all sub-directories under it as well or, if you're retrieving a directory listing with the "ls" command, you could add the "-l" command-line option to obtain a detailed listing instead of the abbreviated version.
Now, I'm not going to wax eloquent on the wonders of command-line options - the concept is a trivial one, and not so hard to understand that it needs more than a couple of lines of explanation. Rather, I'm going to get into something infinitely more interesting - showing you, the developer, how to add support for command-line options to your Perl program.
It's not as difficult as it might seem at first glance - and no, you don't need to stay up all night to get it done. All you really need is a copy of the Getopt::Long.pm Perl module, and a little imagination. Come on in, and be prepared to be amazed...this is potent stuff!
