Hello jayu_rao,

The method File::ReadBackwards->new() takes a filename (i.e., a string) as its first (and only required) argument. But if you first say:

open my $read_log_file, '<', '/home/jay/my_perl_programs/log.txt' or d
+ie $!;

[download]

you create $read_log_file as a file handle, which is something quite different. (It’s like a special kind of pointer that Perl uses to access a file.) You can see this if you try to print it as a string:

16:13 >perl -Mstrict -wE "open(my $fh, '<', '1184_SoPW.pl') or die; sa
+y qq[>$fh<];"
>GLOB(0x7ec4f8)<

16:14 >

[download]

If you then call File::ReadBackwards->new($fh) it will try to access a file named “GLOB(0x7ec4f8)” — and fail, because there is no file of that name.

Hope that helps,
