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 git@gitlab.com
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 git@github.com
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 git@github.com
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.
