Re: File Compare

Hi Cicatrix, see my updated answer below.

my %data_hash;
   open(my $fh, '<', "datafile.txt") or die $!;
   while(<$fh>){
    $data_hash{$_} = 1;
   }
   close($fh);
   open(my $fh1, '<', "tmpfile.txt") or die $!;
   while(<fh1>){
    if(defined($data_hash{$_})){
     print"Line match";
     #open new file in write mode and print line on file
     open(my $fh2, '>', "newfile.txt") or die $!;
     print $fh2 $data_hash{$_};
    }else{
    print"Line not match";
    }
   }
   close($fh2);
   close($fh1);

Hi Nikhil. I tried with this below snippet but this is not getting into the if loop at all. `open(TMPL, '<', "HTML.txt") or die $!; %dump = $resp->content; print TMPL %dump; while (<TMPL>) { $dump{$_} = $_; } close(TMPL); open FILE, "> new_HTML.txt" or die $!; open FILE2, "< Users.txt" or die $!; while(<FILE2>) { if(defined($sp_dump{$_})) { print FILE $sp_dump{$_}; } else { print"Line not match"; } } close(FILE2); close(FILE);` [download] Here * HTML.txt is the text file with HTML content from a URL * Users.txt contains some users data * new_HTML.txt is where i need only User specific data (from Users.txt) in the same format as HTML.txt I need the whole content in new_HTML.txt to be as it is in HTML.txt BUT only for those Users in the Users.txt Am doing the right stuff here?
