GETBIT

Returns the bit value at offset in the string value stored at key.

When offset is beyond the string length, the string is assumed to be a contiguous space with 0 bits. When key does not exist it is assumed to be an empty string, so offset is always out of range and the value is also assumed to be a contiguous space with 0 bits.

Examples

127.0.0.1:6379> SETBIT mykey 7 1
(integer) 0
127.0.0.1:6379> GETBIT mykey 0
(integer) 0
127.0.0.1:6379> GETBIT mykey 7
(integer) 1
127.0.0.1:6379> GETBIT mykey 100
(integer) 0
