It depends on what you mean by "in". :-) The original Seventh Edition
test(1), which was not part of the shell, was prepared to cope properly
with being invoked under the name `['. However, as I recall it didn't
actually exist under that name in /bin as distributed, so there is some
room for doubt about whether this feature was fully operational. But
it does seem to have come from Steve Bourne.
