Re: open file and write the content into another file

Variable interpolation happens only inside double quotes.
Change this

    open my $fh, '<$filename' or die "Can't open $filename: $!";
    open my $dat1, '>$output' or die "\nERROR: Cannot create/open $out

    open my $fh, "<$filename" or die "Can't open $filename: $!";
    open my $dat1, ">$output" or die "\nERROR: Cannot create/open $out

Variable interpolation happens only inside double quotes. Change this ... to ... And perhaps even better, change to the three-argument form of open: `open my $fh, '<', $filename or die "Can't open '$filename': $!";` (no need to string-interpolate `$filename` in `open` call, quoting `$filename` in error message makes all whitespace explicit).
