Thankyou so much for the help. I really appreciate it. But I am unable to print the line having matched ID via (print $line if exists $ids{$id};). I am trying to figure it out :(

    Hi ag88,

    please check the content of your hash. There may be invisible characters in the lines of your first file (like extra space, carriage return, etc.). The best might be to use something like the Data::Dumper module (which is core, so it should be on your machine).
