Most *nix commands already output binary where needed. Text is just how they're interpreted by the terminal because the terminal understands only text, but when you for example redirect a command into another command, if the 1st one spits out binary, the 2nd one gets binary. Typing cat /dev/urandom garbles the terminal because it's binary and the terminal doesn't know how to print it, but cat /dev/urandom|hd prints just fine because hd turns binary data into a ascii hexdump. A program will be more comfortable with reading the 1st, a human very likely the 2nd.
