Is the wget bundled in busybox a full-functional version? It doesn't support --no-directories option, also --version option returns unrecognized option

Busybox utils are not full-featured versions https://busybox.net/about.html

BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts. BusyBox provides a fairly complete environment for any small or embedded system.

$ docker run -it --rm busybox sh
