I am a newbie to perl. I want to compare two text files and print the difference to a third text file. I am not able to find out the required perl script. can somebody please help. The following is my code, 
use File::Compare;
my $F1="version1.txt";
my $F2="count.txt";
my $F3="differ.txt";

if(compare($F1,$F2)==0)#the addition of the USE line is important for 
+this function to work.
    {print"they are the same";}
elsif(compare($F1,$F2)==1)
    {print"they are different";
    #opening/creating all three
     open (FH1,$F1)||die "cannot open $F1.\n";
     open (FH2,$F2)||die "cannot open $F2.\n";
     open (FH3,'>',$F3)||die "cannot create/open $F3.\n";
     while (<FH1>)
          {
         last if eof(FH2);
         $content2=<FH2>; #reads the complete file to content2.    
         chomp($_, $content2);
        #haven't yet figured out how to pull out the difference data.
                 
        }
      
     close(FH1);
     close(FH2);
     close(FH3);
    }
elsif(compare($F1,$F2)==-1)
    {print"error";}
else    {print"something wrong";}

print"Please check the file differ.txt";
