在第二台服务器上的嵌套ssh运行命令 [英] Nested ssh run commands on 2nd server

问题描述

我只能从hostA进入hostB，并且我想在hostB上运行命令.

I can only get to hostB from hostA, and I want to run commands on hostB.

ssh -t $hostA ssh -t $hostB "

   echo 'Hello World!'

   echo 'Test!'

"

此刻，它将先连接到hostA，然后再连接hostB，脚本将暂停.当我键入退出(从hostB)后，我返回到hostA，将打印2条echo命令，然后自动从hostA退出.

At the moment, this will connect to hostA then hostB and the script will pause. As soon as i type exit (from hostB) I return to hostA, the 2 echo commands are printed and then automatically exits from hostA.

如何在hostB上运行命令?

How can I run commands on hostB?
