Hi, some of you helped me with my problem by having my input file which has the following data: 
name1 1 2 3 4 typex
name2 3 4 5 6 typey
name3 2 3 3 1 typex
name4 5 3 4 2 typez
name5 9 8 2 1 typea

[download]
and print it into file "outfile" in the following way: 
typea
name5 9 8 2 1 

typex
name1 1 2 3 4
name3 2 3 3 1 

typey
name2 3 4 5 6 

typez
name4 5 3 4 2

i'm trying to arrange it differently so that it's printed in the following format: 
typex
......
typey
.....
typea
.....
typez
......

i'm currently using the following code to generate it: 
while (<TEMP>)
  {
    my @fields = split; 
    my $key = pop @fields; 
    my $line = [@fields]; 

    push @{$data{$key}}, $line; 
  }
  close TEMP;

  foreach my $key (sort keys %data);
  {
    print "$key\n";
    my @lines = @{$data{$key}}; # list of lines, from hash
    foreach my $line (@lines);
    {
      my @fields = @$line; 
      print "%s %d %d %d %s" @fields;
    }
    print "\n";
  }

anyone have any suggestions as to how to print it in the other format? thanks in advance
