18-
19 A front end to the printf function that lets it be used from the shell.-
20-
21 Backslash escapes:-
22-
23 \" = double quote-
24 \\ = backslash-
25 \a = alert (bell)-
26 \b = backspace-
27 \c = produce no further output-
28 \e = escape-
29 \f = form feed-
30 \n = new line-
31 \r = carriage return-
32 \t = horizontal tab-
33 \v = vertical tab-
34 \ooo = octal number (ooo is 1 to 3 digits)-
35 \xhh = hexadecimal number (hhh is 1 to 2 digits)-
36 \uhhhh = 16-bit Unicode character (hhhh is 4 digits)-
37 \Uhhhhhhhh = 32-bit Unicode character (hhhhhhhh is 8 digits)-
38-
39 Additional directive:-
40-
41 %b = print an argument string, interpreting backslash escapes,-
42 except that octal escapes are of the form \0 or \0ooo.-
43-
44 %q = print an argument string in a format that can be-
45 reused as shell input. Escaped characters used the proposed-
46 POSIX $'' syntax supported by most shells.-
47-
48 The 'format' argument is re-used as many times as necessary-
49 to convert all of the given arguments.-
