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。

Terminal Colors

There exists common confusion about terminal colors. This is what we have right now:

• Plain ASCII
• ANSI escape codes: 16 color codes with bold/italic and background
• 256 color palette: 216 colors + 16 ANSI + 24 gray (colors are 24-bit)
• 24-bit true color: "888" colors (aka 16 milion)

ANSI Escape Sequences

Standard escape codes are prefixed with Escape:

• Ctrl-Key: ^[
• Octal: \033
• Unicode: \u001b
• Hexadecimal: \x1b
• Decimal: 27

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2020-05-31: I won't be maintaining this page or responding to comments anymore. The list of supporting software reflects the known state as of this date. ]

---

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.
