I know that dash adheres quite closely to the POSIX standard, but I know that it's not 100.00% strict POSIX without any extras. The shell that comes closest/adheres exactly to the POSIX standard is as far as I know yash with the POSIXly_correct flag set.

I already tried extensive googling (as far as I'm knowledgable enough for this topic) but who would have thought, it's exclusively results on what the differences between bash and dash are and how dash is very POSIX compliant and so on.
