| 5 | GETBIT key offset | This command is used to return the bit value at the offset in the string value stored at the key. |
| 6 | MGET key1 [key2..] | This command is used to get the values of all the given keys |
| 7 | SETBIT key offset value | This command is used to set or clear the bit at the offset in the string value stored at the key |

| 16 | INCRBY key increment | This command is used to increment the integer value of a key by the given amount |
| 17 | INCRBYFLOAT key increment | This command is used to increment the float value of a key by the given amount |
| 18 | DECR key | This command is used to decrement the integer value of a key by one |
