问题

A(本地计算机) <-> B(跳板服务器) <-> C（git repo仓库所在服务器)

我想要通过B来代理A发送给C的git clone请求而不是用ssh-agent转发。为什么A不直接向C发起请求呢？通常是出于安全或下载速度上的考虑，对于中文用户而言，一般都是GFW（笑，梯子还是没有ssh tunneling裸奔快。

解决办法

# Usage: combined with rm / cp / xargs / ... using pipe

# Find files with specific name e.g. foo and print them 
find . -name "foo" -print

find . -type d -print

# Find files under specific path e.g ~/foo/
find . -path "~/foo/*" -print
