Hi, I am new to perl. I have two files, I need to do comparison to find out the matching and non-matching data. I got two problems now: Question 1: one of my hashes can only capture the 2nd row of the 'num', i tried to use `push @{hash1{name1}},$x1,$y1,$x2,$y2` , but it still returning the 2nd row of the 'num'.

File1 :

    name    foo
    num     111 222 333 444
    name    jack
    num     999 111 222 333
    num     333 444 555 777

File2:

 

    name    jack
    num     999 111 222 333
    num     333 444 555 777
    name    foo
    num     666 222 333 444

This is my code:

    #!/usr/bin/perl
    use strict;
    use warnings;
    use Data::Dumper;
    my $input1=$ARGV[0];
    my $input2=$ARGV[1];
    my %hash1;
    my %hash2;
    my $name1;
    my $name2;
    my $x1;
    my $x2;
    my $y2;
    my $y1;
    
    open my $fh1,'<', $input1 or die "Cannot open file : $!\n";
    while (<$fh1>)
    {
    chomp;
    if(/^name\s+(\S+)/)
    {
     $name1 = $1;
    
    }
    if(/^num\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)/)
    {
    
     $x1 = $1;
     $y1 = $2;
     $x2 = $3;
     $y2 = $4;
    }
    $hash1{$name1}=[$x1,$y1,$x2,$y2];
    
    }
    close $fh1;
    print Dumper (\%hash1);
    
    open my $fh2,'<', $input2 or die "Cannot open file : $!\n";
    while (<$fh2>)
    {
    chomp;
    if(/^name\s+(\S+)/)
    {
     $name2 = $1;
    
    }
    if(/^num\s+(\S+)\s+(\S+)\s+(\S+)\s+(\S+)/)
    {
    
     $x1 = $1;
     $y1 = $2;
     $x2 = $3;
     $y2 = $4;
    
    }
    
    $hash2{$name2}=[$x1,$y1,$x2,$y2];
    
    }
    close $fh2;
    print Dumper (\%hash2);

My output:

    $VAR1 = {
              'jack' => [
                          '333',
                          '444',
                          '555',
                          '777'
                        ],
              'foo' => [
                         '111',
                         '222',
                         '333',
                         '444'
                       ]
            };
    $VAR1 = {
              'jack' => [
                          '333',
                          '444',
                          '555',
                          '777'
                        ],
              'foo' => [
                         '666',
                         '222',
                         '333',
                         '444'
                       ]
            };

My expected Output:

    $VAR1 = {
              'jack' => [ 
                          '999',
                          '111',
                          '222',
                          '333',
                          '333',
                          '444',
                          '555',
                          '777'
                        ],
              'foo' => [
                         '111',
                         '222',
                         '333',
                         '444'
                       ]
            };
    $VAR1 = {
              'jack' => [ 
                          '999',
                          '111',
                          '222',
                          '333',
                          '333',
                          '444',
                          '555',
                          '777'

              'foo' => [
                         '666',
                         '222',
                         '333',
                         '444'
                       ]
            };

Question 2: I tried to use this foreach loop to do the matching of keys and values and print out in a table format. I tried this :

print "\t\tFIle1\t\t\t\t\tFile2\n";
print "Name\tX1\tY1\tX2\tY2\t\t\tX1\tY1\tX2\tY2\n";
    foreach my $k1(keys %hash1)
{
       foreach my $k2(keys %hash2)
       {
               if($hash1{$name} eq $hash2{$name2})
                       {
                               if($hash1{$x1}{$y1}{$x2}{$y2} == $hash2
+{$x1}{$y1}{$x2}{$y2})
                                       {
                                               print "$name\$x1\$y1\$x
+2\$y2\n";
                                       }
                       }
       }
}

but Im getting the header only.

                 File1                        File2
Name     X1      Y1      X2      Y2     X1     Y1     X2     Y2
[download]

my desired output for matching :

                  File1                        File2
    Name     x1   y1   x2   y2            x1   y1   x2   y2
    jack     999  111  222  333           999  111  222  333
             333  444  555  777           333  444  555  777

Any help?
