Are there versions of Unix that don't have awk installed by default?
I am fine with an answer containing some really old outdated Unix variant which predates awk's creation; but would ideally prefer some specialist niche stripped down embedded modern one which excludes awk by design from core install.
(the impetus for asking: someone claimed that an SO answer using nothing but standard unix command line tools sans
awk is useless, since every Unix has
awk. I am pretty sure that last part is wrong, but don't recall any specific examples, just the fact that they exist).
