[opensuse] Need reference for 'printf -v var "format" value` (info coreutils/printf invocation - is silent)

All, I need a reference citation for the use of `printf -v` that writes the formatted output for a value to a variable. The use is: printf -v varname "format specifier" value example: $ printf -v f "0x%02x" 13 $ echo $f 0x0d I know how to use it, I just can't find a reference that tells me I can use it like that. I've checked the man pages and info coreutils/printf invocation, but I can't find a reference to the `-v` option anywhere. What say the gurus? -- David C.
