If your part numbers will never have spaces in them, you could split your lines and build up a hash of arrays:
use strict; use warnings; print "ARGV: $#ARGV\n"; if ($#ARGV != 0) { print "One, and only one (not $#ARGV), command line parameter is +expected\n"; exit; } my $inputFile=$ARGV[0]; if ( not -e $inputFile) { die "$inputFile doesn't exist!!!\nExiting.\n"; } print "Attempting to open $inputFile\n"; open my $file, $inputFile or die "Could not open $inputFile: $!"; my %parts; while (<$file>) { next if /^Part/; my ($part, $info) = split /\s+/, $_, 2; $info =~ s/\s//g; push @{ $parts{$info} }, $part; } for my $info (sort keys %parts) { print "@{ $parts{$info} } - $info - ", scalar @{ $parts{$info} }, +"\n"; } __END__ ARGV: 0 Attempting to open 1.txt P10 - CircleBlue4 - 1 P9 - CircleGreen3 - 1 P1 P4 - CircleRed1 - 2 P7 - RectangleBlue4 - 1 P3 - RectangleRed4 - 1 P5 - SquareBlue1 - 1 P2 P6 - SquareGreen3 - 2 P8 - SquareRed2 - 1

With a little more work, you could sort on hash values to get the output in the order you want.

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.
