Problems? Is your data what you think it is?

I'll modify your example code to help you do some simple sorting. Now, this is likely not the most efficient way to do it, but since you have a small dataset and you are new to perl, this can help you get started.

use strict; use warnings; open (SOMELIST, "somelist") or die "Cannot open file $!\n"; my %sort_data; while (my $record = <SOMELIST>) { my @one_line = split(/,/, $record); while (exists $sort_data{$one_line[1]}) { $one_line[1] = "$one_line[1]" . " "; #add a blank for + uniqueness } $sort_data{$one_line[1]} = $record; #store it by 2nd column } close (SOMELIST); foreach my $line (sort {$a cmp $b} keys %sort_data) { print "$sort_data{$line}"; }

Like I said, this isn't the most efficient or even best method, but it is simple enough that you can hopefully see what is going on.

(2006-11-18 17:21 GMT) Edited my perl code to remove a couple of syntax errors. - Thanks Grandfather for pointing them out.

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