    Shure, yes.

    #!/usr/bin/perl use strict; use warnings; use Data::Dumper; use IO::All; io(shift)->read(my $chunk, 10); print Dumper(unpack("C*", $chunk)); for(unpack("C*", $chunk)){print chr()} $chunk =~ m/(\n|\r\n)/g; print unpack("C*", $1); __END__ $ ./ dos.csv $VAR1 = 102; $VAR2 = 111; $VAR3 = 111; $VAR4 = 59; $VAR5 = 98; $VAR6 = 97; $VAR7 = 114; $VAR8 = 13; $VAR9 = 10; foo;bar 1310 $ ./ unix.csv $VAR1 = 102; $VAR2 = 111; $VAR3 = 111; $VAR4 = 59; $VAR5 = 98; $VAR6 = 97; $VAR7 = 114; $VAR8 = 10; $VAR9 = 10; foo;bar 10

    Don't no other way. Thank you and regards, Karl
