我想使用将iso文件从服务器复制到我的计算机rsync。我使用了以下命令，但是出了点问题，我无法弄清楚是什么。我已经检查了密钥文件和原始文件的位置。
rsync --progress -avz -e 'ssh -v -i ./.ssh/new_keys node@<ip_address>' node@<ip_address>:~/ubuntu-16.04.1-server-amd64.iso ./Downloads/Ubuntu_Server.iso
这是由-v参数创建的日志。

您只需要以下命令。
rsync --progress -avz -e 'ssh -v -i ./.ssh/new_keys' node@<ip_address>:~/ubuntu-16.04.1-server-amd64.iso ./Downloads/Ubuntu_Server.iso
所以删除node@<ip_address>表格-e ssh '-v -i ...'
