I executed the following printf (in a Korn shell command-line)
printf 't %2$s .\n' 3 55
and got the following response
printf: illegal format character $
The following is an excerpt from the man-3 page for printf .
Each conversion specification is introduced by
character %. The arguments must correspond properly (after type promo-
tion) with the conversion specifier. After the %, the following appear
o An optional field, consisting of a decimal digit string followed by
$, specifying the next argument to access . If this field is not
provided, the argument following the last argument accessed will be
used. Arguments are numbered starting at 1. If unaccessed
in the format string are interspersed with ones that are accessed
results will be indeterminate.
The printf should have produced "t 55 ." as output.
Can we please get it fixed?!?!
