Greetings DeusVult,

I'm not sure how security-wise this may be, but I think it's better than running an eval of user-changable data. Give this a try and let me know what you think. I've assumed a few things here, and I've also made @file_contents so you can see some dummy file data.

#!/usr/bin/perl -w
use strict;

my @file_contents;
$file_contents[0] = 'My name is $name.';
$file_contents[1] = 'I live in the city of $city.';
$file_contents[2] = '$city is in the state of $state.';

my $file_contents = join("\n", @file_contents);

my %stuff_to_parse = (
    name => 'Gryphon',
    city => 'Seattle',
    state => 'Washington'
);

foreach (keys %stuff_to_parse) {
    $file_contents =~ s/\$$_\b/$stuff_to_parse{$_}/g;
}

@file_contents = split(/\n/, $file_contents);

foreach (@file_contents) {
    print $_, "\n";
}

Does this help? Also, anyone out there: Can someone tell me if I made any security mistakes here? Also, the \b on the end of the search pattern could be altered to be a little more robust.

-Gryphon.
