Actually, that should still work in bash...just not on the variable
named test, but on the test executable (actually the built-in IIRC). The
output should be a single blank line. I vaguely remember seeing this
behavior myself a long time ago, but don't recall the cause. Best guess
is Armin's suggestion, followed by patches not applied correctly, but
I'm not certain. Either way, the interpreter being used now is broken.
Backtick (`) syntax will probably still work for the test case, but that
doesn't really do anything for the OP. The chapter 5 bash is broken and
must be rebuilt.
