ssh -t 获取 bashrc 文件失败

ssh -t 获取 bashrc 文件失败
ssh -vvv -F /home/me/.ssh/config serva -t "source ~/.bashrc"

-vvv这是我使用标志时得到的输出:

服务器端日志有以下消息:sshd[18763]: Received disconnect from...

我使用的是CentOS 6.4

编辑

我原来的问题是有缺陷的。对于那个很抱歉。我想用我想要的 rc 文件(~/.bashrc_temp)执行 bash shell,然后执行其他东西。我认为 PROMPT_COMMAND 看起来是推荐的选项,或者在 ~/.bashrc_temp 本身内执行命令,这不太理想,但我可能可以添加一些条件语句。

当你这样做时:

ssh serva -t "source ~/.bashrc"

ssh告诉sshd调用远程用户的登录 shell,如下所示:

the-shell -c 'source ~/.bashrc'

这告诉 shell 运行该命令并退出。

也许,您想要的是运行交互式 shell 并让该交互式 shell 运行该source ~/.bashrc命令进而发出提示并阅读更多要执行的命令。

首先请注意,在 的情况下source ~/.bashrc,这是不需要的,因为在交互时bash已经提供了来源~/.bashrc(实际上,在 的情况下ssh,即使在非交互时也会这样做)。所以:

ssh serva

足够。

现在,如果您想运行命令,然后运行交互式 shell,那么您可以执行以下操作:

ssh -t serva 'cmd; bash'

(在那里,需要 ,-t因为ssh在传递要执行的命令时默认情况下不会启动伪终端)

cmd不过,它不会被执行bash(它将由 sshd 启动的 shell(您的登录 shell)执行以解释该cmd; bash 命令行)。

如果您希望交互式bash运行该命令。一个技巧是使用bashsPROMPT_COMMAND变量。bash将该变量的内容解释为要在每个提示之前执行的 shell 代码。所以你可以这样做:

ssh -t serva 'PROMPT_COMMAND="cmd; unset PROMPT_COMMAND" bash'
