Table 10-5. Logical Operators | Example | Name | Result |
|---|
| $a and $b | And | True if both $a and $b are true. | | $a or $b | Or | True if either $a or $b is true. | | $a xor $b | Xor | True if either $a or $b is true, but not both. | | ! $a | Not | True if $a is not true. | | $a && $b | And | True if both $a and $b are true. | | $a || $b | Or | True if either $a or $b is true. |
The reason for the two different variations of "and" and "or" operators is that they operate at different precedences. (See Operator Precedence.) |
