通过ssh无法使用osascript集卷

Question

这是我的情况。

用户A当前登录在计算机A上。

用户B通过ssh登录到计算机A。

用户B通过终端A记录(osascript -e 'set volume 0')运行

这是我的错误日志：

侧注释用户B被设置为admin

很久以前，我记得在没有任何错误的情况下执行这个情况。不确定这是否是具有权限的ARD设置？

Answer 1

我找到了一个可行的选择..。

如果我加上

sudo -u username在osascript -e命令之前，然后它就工作了。

示例

sudo -u username osascript -e 'set volume 0' 

从阅读上看，苹果似乎不允许用户在另一个用户登录时通过ssh会话打开应用程序。必须以当前用户身份登录才能运行osascripts，否则，添加以下命令sudo -u username
