G'day jtucker,
Welcome to the monastery.
As you haven't shown any code, it's difficult to know where you're getting stuck with this. For instance, your earlier comment "What I an hung on is the third bullet." [sic] is meaningless to me: it's the first and only time you've mentioned bullets; there are no bulleted lists; how does the 3rd bullet (not shown) differ from the 1st and 2nd bullets (also not shown). In order to get a better answer when you post here, you'd do well to read these guidelines: How do I post a question effectively?
The following skeleton code may help resolve whatever problem you're experiencing. If not, please post any follow-up questions in line with the guidelines I've linked to above.
$ perl -Mstrict -Mwarnings -E ' my @data = ( q{1:1 word1}, q{1:1 word2}, q{1:1 word3}, q{1:1 word4}, q{1:2 word1}, q{1:2 word2}, q{1:2 word3}, q{1:3 word1}, q{1:3 word2}, q{1:3 word3} ); my $old_head = q{}; for (@data) { my $new_head = (split)[0]; if ($new_head ne $old_head) { say "> $new_head"; $old_head = $new_head; } say; } ' > 1:1 1:1 word1 1:1 word2 1:1 word3 1:1 word4 > 1:2 1:2 word1 1:2 word2 1:2 word3 > 1:3 1:3 word1 1:3 word2 1:3 word3
