In this case, closely enough.

It’s just /bin/sh on long outdated versions (newer ones, both
from Horracle and not, have AT&T ksh93 there instead). No need
to use it, anyway. sh scripts can usually depend on a POSIX
shell (and it’s sensible to do so). Some operating environments
have guaranteed that (MirBSD even guarantees mksh but Debian
Policy §10.4 explicitly states POSIX plus a few extensions).
And AFAIK all FreeBSD® shells have it.
