将变量从 SSH 服务器分配给本地机器变量 [英] Assign variable from SSH server to local machine variable

问题描述

我有两个正在运行的脚本.一个从客户端工作站运行并调用服务器上的脚本.我需要来自服务器脚本的变量，我想我可以这样做，但它不起作用:

I have two scripts that are being run. One runs from a client workstation and calls a script on a server. I need a variable from the server script and I figured I could do it this way, but it isn't working:

#!/bin/sh

local_var=""

ssh user@server " $local_var=\$server_var "

echo "$local_var"

我的 local_var 输出为空.有没有办法做到这一点?

My output of local_var is null. Is there a way to do this?

推荐答案

尝试:

local_var=$(ssh user@server "echo ${server_var}")
