24 | $FUNCTION printf_builtin | |
95732b49 | 25 | $SHORT_DOC printf [-v var] format [arguments] |
3185942a JA |
26 | Formats and prints ARGUMENTS under control of the FORMAT. |
27 | ||
28 | Options: | |
29 | -v var assign the output to shell variable VAR rather than | |
30 | display it on the standard output | |
31 | ||
32 | FORMAT is a character string which contains three types of objects: plain | |
33 | characters, which are simply copied to standard output; character escape | |
34 | sequences, which are converted and copied to the standard output; and | |
cce855bc | 35 | format specifications, each of which causes printing of the next successive |
3185942a JA |
36 | argument. |
37 | ||
ac50fbac CR |
38 | In addition to the standard format specifications described in printf(1), |
39 | printf interprets: | |
3185942a JA |
40 | |
41 | %b expand backslash escape sequences in the corresponding argument | |
42 | %q quote the argument in a way that can be reused as shell input | |
495aee44 CR |
43 | %(fmt)T output the date-time string resulting from using FMT as a format |
44 | string for strftime(3) | |
3185942a | 45 | |
ac50fbac CR |
46 | The format is re-used as necessary to consume all of the arguments. If |
47 | there are fewer arguments than the format requires, extra format | |
48 | specifications behave as if a zero value or null string, as appropriate, | |
49 | had been supplied. | |
50 | ||
3185942a JA |
51 | Exit Status: |
52 | Returns success unless an invalid option is given or a write or assignment | |
53 | error occurs. | |
