osascript设置音量无法通过ssh进行工作 [英] osascript set volume isn't working via ssh

问题描述

这是我的情况.

用户A 当前已登录计算机A .

用户B 通过ssh登录到计算机A .

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

User B runs via terminal a osascript (osascript -e 'set volume 0')

这是我的错误日志:

旁注 用户B设置为管理员

Side notes User B is set as admin

从前，我记得在没有任何错误的情况下执行这种情况.不确定这是否是具有权限的 ARD设置?

Once upon a time, I recall executing this situation before without any errors. Not sure if this is a ARD setting with privileges?

推荐答案

我找到了一种似乎可行的替代方法...

I've found an alternative which seems to work...

如果我添加

sudo -u username，则它起作用.

示例

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

从看来，Apple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 ，添加以下命令sudo -u username

from what a read, seems that apple does not allow users to open applications via ssh session while another user is logged in. Must be logged in as the current user to run osascripts, otherwise, add the following command sudo -u username
