大概用 Termius 在 ios 平台连接云是好多人目前的选择，优点很多，缺点是只有14天免费使用期，过后，依照今天的价格是 38元/月，388元/年。对于我等使用频次不高的用户群体来说，如此的定价还是有些偏高的。而我个人偏好，不大喜欢用月月（年年）续费的软件，一次买断，比较符合个人的消费习惯。最近得知一款 App : Blink shell，大致了解后，果断购之（128元）。现将使用心得分享如下。App 安装打开后，默认显示黑底白字的终端：
blink>
实例
blink>config blink>ssh root@ip blink>ssh linux # 需提前在 UI 界面配置主机信息 blink>mosh root@ip blink>mosh linux # 需提前在 UI 界面配置主机信息
对于用惯了带UI界面的人来说，仅仅出现这么一个界面，没有任何向导还是比较懵的。试着敲入：help
blink> help
