How do I print the (numerical) ASCII values of each character in a file?

How can I print the numerical ASCII values of each character in a text file. Like cat, but showing the ASCII values only... (hex or decimal is fine).

Example output for a file containing the word Apple (with a line feed) might look like:

065 112 112 108 101 013 004

sed bash linux

hexdump, od, xxd, or $YOUR_FAVORITE_LANGUAGE can all do that.

% echo Apple | hexdump -C

00000000  41 70 70 6c 65 0a                                 |Apple.|

00000006

% echo Apple | perl -ne 'printf "%vd\n", $_' 

65.112.112.108.101.10

% echo Apple | clisp <( echo '(print (mapcar #'\''char-code (coerce (read-line standard-input) '\''list)))' )

(65 112 112 108 101)
