git remote

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)
