           Summary: Please add support for -v option in printf
           Product: Busybox
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW

  Target Milestone: ---

Please add support for -v option in printf:
-v VAR  If given, the output is assigned to the variable VAR instead of printed
to stdout (comparable to sprintf() in some way)

Example:
val1="111"
val2="222"
printf -v var '%s_%s' "$val1" "$val2"
echo "$var"
