Usually you would do that by:
% script.pl < textfile
People often abuse cat(1) in this sort of case: it's the first time
I've seen anyone do it with less.

This typically means that the #! line in the script is incorrect --
for a perl script you need:
#!/usr/bin/perl
as the first line -- possibly with some extra flags. This assumes you
actually have perl installed. perl-5.005.03 comes with the base
system in 4.x, but in 5.x you have to install one of the perl ports --
perl-5.8.2 is now the default perl under 5.2 or above. In any case,
remember to run the 'use.perl' script after installing or before
de-installing a perl port.
Nb. There are all sorts of weird ways of setting up the #! line of a
perl script floating around the perl community, but those really are a
waste of time on FreeBSD (or most modern unices for that matter).
Stick with the tried and true simple way unless you have an overriding
reason to do otherwise.
Cheers,
Matthew
