    Hexdump is a hexadecimal representation of bytes in a file. You can obtain it by running something like this:
    open my $f,"<:raw","file.csv" || die $!; my $c; for (1..8) { for (1..16) { read $f,$c,1 || exit 0; print unpack "H2",$c; } print "\n"; }
    You can rewrite unix2dos in Perl using PerlIO :crlf output layer.
    Sorry if my advice was wrong.
