If all you want to do is print from standard input then try this: 
#!/usr/bin/perl -w
use strict;
while (<>) {
  print $_;
}

It boils to Perl reading from the files listed on the command line or from the keyboard (don't forget Ctrl-Z to end in that case).

<Update>I forgot to mention that it can be called like this: script_name.pl input_file
