[Feature Request] POSIX ls usage

[AndreiSva]

Right now kaktree needs a bunch of non-POSIX ls command line options to work. It would be great to POSIX-fy the ls usage in order to enable the plugin to be used on busybox or BSD systems.

Hi, can you be more specific on which tools are non-posix? It requires Perl, and ls with posix keys.

[AndreiSva]

@andreyorst -B is not defined by POSIX, and is not present on a lot of popular alternative coreutils such as busybox.

[andreyorst]

kaktree doesn't require it, and doesn't use it. It seems like a typo in readme.

[andreyorst]

@AndreiSva I've fixed the typo 😄. Are there any actual errors on BSD or busybox systems?

[AndreiSva]

-b is still not defined by POSIX and doesn't work on busybox ls or OpenBSD ls, couldn't test on other coreutils. You can see a list of all portable ls options here.

[andreyorst]

hmm -b can be worked around, I guess non-graphic characters are rare in files, though this needs more testing.

Alternatively we could gather the directory list with Perl, but this would require some reimplementation of the build_tree subroutine
