Not only do you give the impression that you're 10 years old, you are rude to non-native speakers of the English language who could possibly help you. > #!/usr/bin/perl > use strict; > use warnings; > print "Enter the File name \n"; > my $input_file = <STDIN> ; > chomp($input_file) ; > open FH,$input_file or die "Can not open the file at $!" ; > my @lines = <FH>; This line slurps the entire file into the array @lines.

As I said, there is nothing left to read from the FH filehandle. You read it all already, into the array @lines. If you want to start reading again, you have to seek() (see `perldoc -f seek`). Otherwise, this loop will never execute because <FH> returns undefined after FH has had all its data read. > print $. ;} > > close(FH); > > But its neither printing line number nor giving any error. Because there is no syntax nor runtime error there. Perl is doing exactly what you asked it to do.
