Thank you guys for all of the help in getting this fixed up. I started playing with the Math::Combinatorics method before I saw any of the other posts then my gf made me go to bed so I haven't had a chance to play with them too much :/

This is what I have right now though. Something still isn't quite right with the matching from the dict file (I changed it to match 3-6 letter words from a full dictionary instead fyi). The @permutationsX arrays do in fact hold the different permutations of 6choose(3-6) but there's some problem matching the words to those in the dictionary file. 

#!/perl
use strict;
use warnings;
use Math::Combinatorics;

my $input = <STDIN>;
chomp($input);
my @inputarray = split('',$input);

my $file = 'wordlist.txt';
open(INFO, $file);
my @lines = <INFO>;
close(INFO);
chomp(@lines);

print "\n\n\n\nGenerating Wordlist from \'$input\'...\n";
print "----------\n";

#find all 3 letter words and print out
my @permutations3 = map { join "", @$_ } combine(3,@inputarray);
my %dup3;
@dup3{@permutations3} = ();
my @tacobell3 = grep { exists $dup3{$_} } @lines;
foreach (@tacobell3) {
    print "$_\n";
}

#find all 4 letter words and print out
my @permutations4 = map { join "", @$_ } combine(4,@inputarray);
my %dup4;
@dup4{@permutations4} = ();
my @tacobell4 = grep { exists $dup4{$_} } @lines;
foreach (@tacobell4) {
    print "$_\n";
}

#find all 5 letter words and print out
my @permutations5 = map { join "", @$_ } combine(5,@inputarray);
my %dup5;
@dup5{@permutations5} = ();
my @tacobell5 = grep { exists $dup5{$_} } @lines;
foreach (@tacobell5) {
    print "$_\n";
}

#find all 6 letter words and print out
my @permutations6 = map { join "", @$_ } permute(@inputarray);
my %dup6;
@dup6{@permutations6} = ();
my @tacobell6 = grep { exists $dup6{$_} } @lines;
foreach (@tacobell6) {
    print "$_\n";
}

print "----------\n\n\n";

$_ = <STDIN>;
exit();

The point Goib brought up is correct. Given the letters tuegps, I would want to output 'getups' 'getup' 'guest' 'gust' 'tug' etc. The code I have is SO CLOSE! It's just having an issue matching the words :/

Thanks again for all the help!
