$a || $b # logical or: true if either is nonzero

$a && $b # logical and: true only if both are nonzero

Perl 5 also defines these logical operators:
|
||
|
|
$a or $b # another form of logical or
|
||
|
|
$a and $b # another form of logical and
|
||
|
|
not $a # another form of logical not
|
||
|
|
$a xor $b # logical xor: true if either $a or $b is nonzero, but not both
