通过 ssh sudo 的正确方法 [英] proper way to sudo over ssh

问题描述

我有一个脚本，它使用 sudo 在远程服务器上通过 SSH 运行另一个脚本.但是，当我输入密码时，它会显示在终端上.(否则它工作正常)

I have a script which runs another script via SSH on a remote server using sudo. However, when I type the password, it shows up on the terminal. (Otherwise it works fine)

ssh user@server "sudo script"

执行此操作的正确方法是什么，以便我可以通过 SSH 键入 sudo 的密码，而不会在我键入时出现密码?

What's the proper way to do this so I can type the password for sudo over SSH without the password appearing as I type?

推荐答案

另一种方法是使用 -t 切换到 ssh:

Another way is to use the -t switch to ssh:

ssh -t user@server "sudo script"

见man ssh:

 -t      Force pseudo-tty allocation.  This can be used to execute arbi-
         trary screen-based programs on a remote machine, which can be
         very useful, e.g., when implementing menu services.  Multiple -t
         options force tty allocation, even if ssh has no local tty.
