If you find yourself "uniquifying" keys for a hash you should probably be using an array. Consider:

use strict; use warnings; use constant KEY => 1; my @sort_data; while (my $record = <DATA>) { my $key = (split(/,/, $record))[KEY]; push @sort_data, [$record, $key]; } foreach my $pair (sort {$a->[1] cmp $b->[1]} @sort_data) { print "$pair->[0]"; }

using the same data as in previous samples prints:

BUT, It runs with no errors, but nothing prints. I tried your code, and it seems quite simple, hence, efective. At the moment, due to the small file size, sort time is unimportant. At some point, when I get to that stage, the sorted data will be reuse +d.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • 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 or How to display code and escape characters are good places to start.
