Not portable, but if you're willing to write scripts that only work with
GNU coreutils installed, maybe an option.  You'd probably want to add -A
as well.

How about just using one of the bash builtin methods that are presented
on <https://mywiki.wooledge.org/BashFAQ/004>?  Not only are they portable
(so long as bash is installed), but they don't require forking external
commands like ls(1) and wc(1) in the first place.
