Translation: read a chunk of data that you know to be big enough, then search for known character strings that could be the right answer ... taking care to search for longer strings first.

    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
