关于git的一些知识点

git是一个分布式代码管理工具，所以可以支持多个仓库，在git里，服务器上的仓库在本地称之为remote。

直接clone一个仓库：

    $: git clone git@search.ued.taobao.net:projects/search.git

另外一种clone方式：
# 创建目录初始化本地仓库

$: mkdir search && cd search

$: git init

# 添加远程仓库路径

$: git remote add github git@github.com:yyfrankyy/search.git

# 实际上，pull 就是 fetch + merge

$: git pull github --all --tags

把工作目录迁移到github上面：
$: git remote add github git@github.com:yyfrankyy/search.git

$: git push github --all --tags

显示所有的远程仓库
$: git remote -v

origin git@search.ued.taobao.net:projects/search.git (fetch)

origin git@search.ued.taobao.net:projects/search.git (push)

github git@github.com:yyfrankyy/search.git (fetch)

github git@github.com:yyfrankyy/search.git (push)

重命名远程仓库
$: git remote rename github gh

$: git remote

origin

gh

删除远程仓库
$: git remote rm github

$: git remote

origin

从远程仓库抓取数据，更新本地仓库：
$: git fetch origin

remote: Counting objects: 58, done.

remote: Compressing objects: 100% (41/41), done.

remote: Total 44 (delta 24), reused 1 (delta 0)

Unpacking objects: 100% (44/44), done.

From git://search.ued.taobao.net:projects/search.git

* [new branch]      product    -> origin/product

查看远程仓库信息，可用于跟踪别人的push：
$: git remote show origin

* remote origin

  Fetch URL: git@search.ued.taobao.net:projects/search.git

  Push  URL: git@search.ued.taobao.net:projects/search.git

  HEAD branch: master

  Remote branches:

    master  tracked

    p4popt  tracked

    prepub  tracked

    product tracked

   Local branches configured for 'git pull':

    master  merges with remote master

    p4popt  merges with remote p4popt

    prepub  merges with remote prepub

    product merges with remote product

    Local refs configured for 'git push':

    master  pushes to master  (up to date)

    p4popt  pushes to p4popt  (up to date)

    prepub  pushes to prepub  (up to date)

    product pushes to product (up to date)
