GETBIT key offset

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.

The bit value stored at offset, one of the following:

• valkey-protocol(7) Integer reply: 0.
• valkey-protocol(7) Integer reply: 1.
