#!/usr/bin/perl use 5.8.0; use strict; use warnings 'all'; use sort 'stable'; my ($first, $second) = @ARGV; open my $fh => $first or die "open first: $!\n"; chomp (my @words = <$fh>); close $fh; my $c = 0; my %words = map {$_ => ++ $c} @words; open my $sh => $second or die "open second: $!\n"; my @info; while (<$sh>) { chomp; push @info => [split /\|/]; } close $sh; @info = sort {$words {$a -> [0]} <=> $words {$b -> [0]}} @info; print "@$_\n" for @info; __END__
Give the names of the two files as arguments. And if there's a lot of data, you may want to turn the sort into a GRT.

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