Linux kernel, wifi hack, security & Golang

之前用 SVN 的时候经常用 svn info 反应当前svn的基本信息，但是在Git 中没有类似的功能。

比如查看当前版本的一些基本信息:

[code lang="c"]
git remote -v
git branch -r
git branch
[/code]

每次敲很多的命令是很麻烦的，但是Hack里面力量是无限的，在 git-info.txt 有些简单的命令组合可以完成我们的需求。

运行的效果如下:

[code lang="c"]

== Remote URL: origin   git://git.kernel.org/pub/scm/linux/kernel/git/rdunlap/linux-docs/.git
== Remote Branches:
origin/HEAD
origin/doc-subdirs
origin/master

== Local Branches:
* doc-subdirs

== Configuration (.git/config)
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
[remote "origin"]
url = git://git.kernel.org/pub/scm/linux/kernel/git/rdunlap/linux-docs/.git
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "doc-subdirs"]
remote = origin
merge = refs/heads/doc-subdirs

== Most Recent Commit

Git-info 脚本如下:
