ssh 循环文件并在本地传输

ssh 循环文件并在本地传输

我通过 ssh 登录到服务器 1，在服务器 1 上，我想获取位于服务器 2 上的 git 存储库中的文件，并将它们保存在服务器 1 上以对它们进行某些操作（保存到数据库的脚本）

git 存储库的结构相当深。我无法直接克隆存储库，因为空间不足。因此，我当然想循环遍历 Server2 上的所有文件，并将每个文件移动到 server1，执行我的功能以保存到数据库，然后删除该文件。

我遇到问题的部分是递归循环通过 ssh 下载文件。

编辑时：我正在两个 redhat 服务器之间进行通信。

这不是很优雅，但希望这个想法能够被理解：

ssh localhost -p4444 \
 "find ~/tmp/  -iname \*png -exec \
    sh -c 'echo mkdir -p moo-diles/\`dirname {}\`\;\
           rsync -e \"ssh -p 4444\" localhost:{} moo-files/{}\;\
           rm -i {}' \; "

(...)

这里所做的可以称为“元编程”，因为对于每个找到的文件，我们只需回显更多要执行的命令。这些命令必须在稍后执行才能处理每个文件。明智的做法是将传入的命令sh -c '<here>'放在服务器上的脚本中。这样，您就不会在尝试正确退出并阅读长达三行的命令时失去理智。
