/* Usage: printf format [argument...]

​

   A front end to the printf function that lets it be used from the shell.

​

   Backslash escapes:

​

   \" = double quote

   \\ = backslash

   \a = alert (bell)

   \b = backspace

   \c = produce no further output

   \f = form feed

   \n = new line

   \r = carriage return

   \t = horizontal tab

   \v = vertical tab

   \0ooo = octal number (ooo is 0 to 3 digits)

   \xhhh = hexadecimal number (hhh is 1 to 3 digits)

​

   Additional directive:

​

   %b = print an argument string, interpreting backslash escapes

​

   The 'format' argument is re-used as many times as necessary

   to convert all of the given arguments.
