Description
/usr/bin/printf does not recognize positional arguments. printf(3c) says:
-- snip --
Conversions can be applied to the nth argument after the
format in the argument list, rather than to the next unused
argument. In this case, the conversion specifier % (see
below) is replaced by the sequence %n$, where n is a decimal
integer in the range [1, NL_ARGMAX], giving the position of
the argument in the argument list. This feature provides for
the definition of format strings that select arguments in an
order appropriate to specific languages (see the EXAMPLES
section).
-- snip --
However an attempt to use this feature with /usr/bin/printf results in
gibberish:
$ /usr/bin/printf "%2\$x %1\$d\n" 14 2
ffbffcd7 -4195116
ksh -c 'printf "%2\$x %1\$d\n" 14 2'
Frequency
Always
Regression
No
Steps to Reproduce
Run /usr/bin/printf like this:
$ /usr/bin/printf "%2\$x %1\$d\n" 14 2
Expected Result
The arguments "14" and "2" printed in reverse order:
-- snip --
2 14
-- snip --
Actual Result
Some hexadecimal numbers which look completely unrelated to the input
arguments:
-- snip --
ffbffcd7 -4195116
-- snip --
Error Message(s)
-
Test Case
See above.
Workaround
Use ksh93's "printf" builtin, e.g.
-- snip --
$ ksh93 -c 'printf "%2\$x %1\$d\n" 14 2'
2 14
-- snip --
