无法通过 scp 复制多个文件

Question

这个连接到我的 aws 服务器的命令运行良好：

ssh -i my_pem.pem ubuntu@ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com

但这不是：

$ scp -v -i my_pem.pem file1 file2 ubuntu@ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com:/home/ubuntu/folder1

更新1：

怎么了？

Answer 1

看看区别

debug1: Connecting to xx-xx-xx-xx.xx-west-1.compute.amazonaws.com [11.22.33.44] port 22.

和

Executing: program /usr/bin/ssh host ip-xx-xx-xx-xx, user ubuntu, command scp -v -d -t /home/ubuntu/folder1
ssh: Could not resolve hostname ip-xx-xx-xx-xx: Name or service not known

您的 scp 正在连接其他地方，由于您混淆了 IP/地址，我不知道这是有意还是真的。

scp 正在解析您的文件，并且可能在您的文件名中发现了一些 : 字符（第一次猜测 @ 是错误的）并将该文件名解析为 host:path？只用其中一个文件试一试，贴出真实文件名。

或者更确切地说使用sftp。它不关心命令行上的语法。只需sftp your host 然后：

cd folder1
put my_file file2
