Using Getopt::Long it input different data sets

chinamox has asked for the wisdom of the Perl Monks concerning the following question:

Greetings Brothers,

I am finishing up some class work and I wanted to check if I was on the right path or not...

I want to use Getopt::Long to load different data sets into the program I just finished writing. I need to be able to load the files paths in the following forms:

./plc.pl < /myflies/lib/words
./plc.pl /myfiles/lib/words
cat /home/programs/perl/myfiles/lib/words | ./plc.pl
[download]

My other option is to investigate using something like this:

#!/opt/bin/perl -w
#
#usage: ./plc.pl url
#
use strict;

my ($url) =@ARGV;
while(my $scalar = <>){
####
Main Program here
####
}
[download]

So am I on the right track with either of these or are they both just a newbee barking up the wrong trees?

As always, thank you in advanced for your guidence and patience.

The simple `while (<>) {}` was designed for this case. If you have no command line arguments, this reads from STDIN, otherwise treats all arguments in `@ARGV` as filenames, tries opening them and reads from all of them sequentially.
