       --help display this help and exit

	      output version information and exit

       FORMAT controls the output as in C printf.  Interpreted sequences are:

       \     backslash

       a     alert (BEL)

            backspace

     carriage return

       	     horizontal tab

       NNN   byte with octal value NNN (1 to 3 digits)

       xHH   byte with hexadecimal value HH (1 to 2 digits)

       uHHHH Unicode (ISO/IEC 10646) character with hex value HHHH (4 digits)

       UHHHHHHHH
	      Unicode character with hex value HHHHHHHH (8 digits)

       %%     a single %

       %b     ARGUMENT as a string with `' escapes interpreted, except that octal escapes are of the form  or NNN

       and  all C format specifications ending with one of diouxXfeEgGcs, with ARGUMENTs converted to proper type first.  Variable widths are han-
       dled.

       NOTE: your shell may have its own version of printf, which usually supersedes the version described here.  Please  refer  to  your  shell's
       documentation for details about the options it supports.
