Hi disedorgue,

Thanks for the script, it works for one-liners but why the script is not work when I try to modify the script as below.
Code:
#!/usr/bin/perl -w
use strict;

my $file = "in.txt";
my %X = ();

open (FH, '<', $file) or die $!;

my @F = <FH>;

foreach my $i (@F) 
{ 
  $X{$i}+=1; 
}  

foreach my $i (@F) 
{
  
  if ($X{$i}==1)
  {
    printf "%s ","$i";
  } 
}
print "\n";
%X= ();

close (FH);

Hi,
it works with small modification. Thanks

Code:
#!/usr/bin/perl -w
use strict;

my %X = ();
open (FH, '<', "in.txt") or die $!;

my @F = <FH>;
my @temp;

foreach my $line (@F) 
{ 
  chomp $line;
  @temp = split " ", $line;  
  for my $i ( 0 .. $#temp)
  {
    $X{$temp[0]}{$temp[$i]}++;    
  }
} 

foreach my $key(keys %X)
{ 
  foreach my $subkey(keys %{$X{$key}})
  {
     print "$subkey " if $X{$key}{$subkey} == 1;
  }
  print "\n";
}

close (FH);
