如何合并Git 代码库中牛人的代码到自己的库

github for Windows使用介绍 这篇文章可以很好带我们入门github，同时还带了一个gitshell，这个工具可以运行github的所有命令，命令才能干更多事情，比如今天我们要完成的一个任务就是如何如何合并Git 代码库中牛人的代码到自己的库。

* [new branch]      master     -> coreteam/master

#建立主项目作为自己的分支
C:\Users\geffzhang\Documents\GitHub\SharpOAuth2 [master]> git checkout -b coreteam coreteam/master
Branch coreteam set up to track remote branch master from coreteam.
Switched to a new branch 'coreteam'
C:\Users\geffzhang\Documents\GitHub\SharpOAuth2 [coreteam]> git branch -a
* coreteam
  master
  remotes/coreteam/master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master

#现在你可以追踪最新的更新并把它们合并到你自己的分支里

# 切换到master分支
C:\Users\geffzhang\Documents\GitHub\SharpOAuth2 [coreteam]> git checkout master
Switched to branch 'master'

将 coreteam/master 合并到本地的 Master 分支

C:\Users\geffzhang\Documents\GitHub\SharpOAuth2 [master]> git merge coreteam/master

下面是一些比较有用的命令的介绍：

# 创建一个版本库

git init

# 每次修改好了后，可以先将修改存入stage(快照/索引)中

git add <modified files>

# 修改了大量文件则使用下面这个命令批量存入

git add .

# 使用commit将快照/索引中的内容提交到版本库中

git commit -m"msg"

# 也可以将git add与git commit用一个指令完成

git commit -a-m"msg"

# 将本地的git档案与github(远程)上的同步

git push

# 将github(远程)的git档案与本地的同步(即更新本地端的repo)

git pull

# 例如,pull指令其实包含了fetch(將变更复制回來)以及merge(合并)操作

git pull git://github.com/tom/test.git

# 另外版本控制系統的branch功能也很有意思，若同时修改bug，又要加入新功能，可以fork出一个branch：一个专门修bug，一个专门加入新功能，等到稳定后再merge合并

git branch bug_fix # 建立branch，名为bug_fix

git checkout bug_fix # 切换到bug_fix

git checkout master #切换到主要的repo

git merge bug_fix #把bug_fix这个branch和现在的branch合并

# 若有remote的branch，想要查看并checkout

git branch -r# 查看远程branch

git checkout -b bug_fix_local bug_fix_remote #把本地端切换为远程的bug_fix_remote branch并命名为bug_fix_local

# 还有其它可以查看repo状态的工具

git log #可以查看每次commit的改变

git diff#可以查看最近一次改变的內容，加上参数可以看其它的改变并互相比较

git show #可以看某次的变更

# 若想知道目前工作树的状态，可以輸入

git status

配置http代理
git config --global http.proxy http://web-proxy.xxxxx.com:8080

git 删除错误提交的commit

方法:

    git reset --hard <commit_id>

    git push origin HEAD --force

其他:

    根据–soft –mixed –hard，会对working tree和index和HEAD进行重置:
    git reset –mixed：此为默认方式，不带任何参数的git reset，即时这种方式，它回退到某个版本，只保留源码，回退commit和index信息
    git reset –soft：回退到某个版本，只回退了commit的信息，不会恢复到index file一级。如果还要提交，直接commit即可
    git reset –hard：彻底回退到某个版本，本地的源码也会变为上一个版本的内容


    HEAD 最近一个提交
    HEAD^ 上一次
    <commit_id>  每次commit的SHA1值. 可以用git log 看到,也可以在页面上commit标签页里找到.
