I originally used Sort::Fields to create the report, but as I mention below most beginners don't like to use modules outside the standard ones.

#!/usr/bin/perl use strict; use diagnostics; use Sort::Fields; my (@records, @report); { my $data_file = 'test.dat'; open my $fh, $data_file or die "Can't open $data_file: $!"; while (<$fh>) { # skip blank and commented lines next if /^\s*#/; next if /^\s*$/; # We'll look for lines that describe a report: if (/report:\s+sort\s+(\S*)/ ) { @report = split /,/, $1; next; } push @records, $_; } } my (@columns, @sort_description); { my %field = ( source => 1, time => 2, sip => 3, sport => 4, dip => 5, dport => 6, hits => 7, acl => 8, lnum => 9 ); foreach (@report) { my ($name, $order) = split /-/; my $suffix = $name =~ /source|time/ ? '' : 'n'; if ($order eq 'd') { push @sort_description, "$name:\t\tdescending\n"; push @columns, "-$field{$name}$suffix"; } else { push @sort_description, "$name:\t\tascending\n"; push @columns, "$field{$name}$suffix"; } } } { ### store report data in file my $report_file_name = "out.txt"; open my $fh, '>', $report_file_name or die "Can't Open $report_file_name: $!"; my $date = localtime; $date =~ s/ /-/g; print $fh qq|\t\tREQUEST FOR SORTING\n\n|, @sort_description, qq|\n\nFILE WAS GENERATED ON: $date\n\n|, fieldsort ',', \@columns, @records; } __END__

Thanks for your reply,

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.
