How to copy data with sshpass between two remote machines?
提问by telina
I am new to bash and currently working on a script. I am working with two remote machines and accessing them via sshpass (I know its not good to hardcode passwords but I am supposed to do it this way). So if I want to copy stuff from my local machine to the remote one I am doing it like this:
我是 bash 新手，目前正在编写脚本。我正在使用两台远程机器并通过 sshpass 访问它们（我知道硬编码密码不好，但我应该这样做）。因此，如果我想将内容从本地机器复制到远程机器，我会这样做：
sshpass -p $PASS scp <file> <destination>
But now I want to copy data from one remote machine to the other. Is this possible or do I have to buffer the data on my local machine? If its possible how should the syntax should look like? I would somehow need sshpass for both arguments, right?
但是现在我想将数据从一台远程机器复制到另一台机器。这是可能的还是我必须在本地机器上缓冲数据？如果可能的话，语法应该是什么样的？我会以某种方式需要 sshpass 来处理这两个参数，对吗？

can you ssh between two remote machines directly?
你可以直接在两台远程机器之间 ssh 吗？
run this from your local machine. (machine1 and mechine2 are remote servers)
从您的本地机器运行它。（machine1 和 mechine2 是远程服务器）
sshpass -p $PASS1 ssh user1@machine1 "sshpass -p $PASS2 scp file user2@machine2:/destination"
set keyless in ssh/scp between two remote servers and your local desktop to remote server. Then you needn't sshpass SSH login without password
在两台远程服务器和本地桌面到远程服务器之间的 ssh/scp 中设置无密钥。那么你不需要sshpass SSH 登录没有密码
ssh user1@machine1 "scp file user2@machine2:/destination"
