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选项的作用，以某种方式无法在手册中看到此选项:

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 !

有人可以解释吗?

推荐答案

我解释了TTY是什么之前:当您打开与远程服务器的 interactive 会话时，需要使用终端.

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等)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)

您仍要执行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，因此在进行此测试时应使用-T选项.

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