Be lazy, stand on the shoulders of others. List::Compare does all that and more. (The code below has been mildly tested.)
#!/usr/bin/perl
use strict;
use warnings;
use diagnostics;
use List::Compare;
my @List1 = qw(education production results);
my @List2 = qw(education joe bob carl production steve results test);
my @OutList1 = @List1; #Part I is done...
my $lc = List::Compare->new(\@List1, \@List2);
# Get those items which appear (at least once) only in the second list
+.
my @OutList2 = $lc->get_complement;
my $n;
foreach (@OutList2) {print $n++.": $_\n"};
Output:
0: bob
1: carl
2: joe
3: steve
4: test
Cheers,
Brent

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
