Syntax

BITOP operation destkey key1 key2 ... keyN

Perform a bitwise operation between multiple keys and store the result in the destination key. BITOP command support all bitwise operations like AND, OR, XOR and NOT.

Returns

The size of the string stored in the destination key.

Examples

BITOP AND destkey key1 key2 key3 ... keyN

BITOP OR destkey destkey key1 key2 key3 ... keyN

BITOP XOR destkey destkey key1 key2 key3 ... keyN

BITOP NOT destkey key1
