Actually I've never regarded "&&" and "||" (and also "|"
and "&") as operators, like real operators in a programming
language, but as command separators, much like ";", but
with special semantics.
Note that
foo && bar && baz
foo || bar || baz
is the same as
if foo; then if bar; then baz; fi; fi
if ! foo; then if ! bar; then baz; fi; fi
Best regards
Oliver
