ssh 命令 -T 选项 [英] ssh command -T option

问题描述

我想知道以下命令中的 -T 选项有什么作用，在手册中看不到这个选项:

I'm wondering what the -T option in the following command does, cannot see this option in the manual somehow:

$ ssh -T [e-mail]
Welcome to GitLab, Simeon !

谁能解释一下?

推荐答案

我在什么是 TTY 之前解释过:一段文字当您打开与远程服务器的交互式会话时，需要终端.

I explained before what TTY was: a text terminal is needed when you open an interactive session to a remote server.

但是:在远程 Git 存储库托管服务器(GitHub、Gitlab、BitBucket...)的上下文中，没有远程服务器将允许您打开交互式会话(出于安全原因)

But: in the context of a remote Git repository hosting server (GitHub, Gitlab, BitBucket, ...), no remote server will ever allow you to open an interactive session (for security reason)

那么，您仍然会执行 ssh -T [e-mail] 的唯一原因是测试您是否通过了正确的身份验证，并且会话将立即结束:

Then only reason why you would still do an ssh -T [e-mail] would be to test if you are correctly authenticated, and the session would immediately end with:

Hi username!  You've successfully authenticated, 
but GitHub does not provide shell access. 

由于该测试不需要 tty，因此您应该在进行此测试时使用 -T 选项.

Since no tty is needed for that test, you should use the -T option when making this test.
