What were you trying to do?
Violate causality (actually, it was more of a typo...)
What's wrong:
% /usr/bin/sleep -3600 && /bin/echo 'One hour has elapsed.'
bad character
One hour has elapsed.
What should have happened:
Since the sleep program terminated abnormally, its exit status
should've been nonzero, and thus /bin/echo shouldn't have been
executed.
