无法通过scp发送文件

Question

我有两个不同主机的根特权。但是，我无法通过scp命令将文件从一个主机发送到另一个主机。有什么问题吗？请帮帮我。

下面是我使用的命令及其输出

我也经历过类似的问题。也就是说，我有带有0的scp退出，但是文件没有被传输。

我发现这个线程是一个bug 这里。还有一个解释这里。

问题在于echo命令位于两个文件/etc/bash.bashrc和~/.bashrc中。具有非交互式外壳的scp启动并从中读取数据。因为非交互式shell将读取这两个配置文件。它们的输出加上来自scp的输出将使scp混淆，因此没有文件输出。

我检查了您的输出，发现有一行：

删除echo命令或添加

# If not running interactively, don't do anything
[[ $- == *i* ]] || return

来防止这个问题。
