Redis 命令列介面

redis-cli 是 Redis 命令列介面程式，允許向 Redis 傳送命令並直接從終端讀取伺服器傳送的回覆。基本命令列用法如下：

訪問 redis：

$ redis-cli
127.0.0.1:6379>

通過身份驗證訪問 redis：

$ redis-cli -a myPassword
127.0.0.1:6379>

選擇資料庫並顯示資料庫大小（預設資料庫編號為 0）：

127.0.0.1:6379> dbsize
(integer) 2
127.0.0.1:6379> select 1
OK
127.0.0.1:6379[1]> dbsize
(integer) 20

獲取有關伺服器的資訊和統計資訊：
