如何从git仓库只签出一个文件（'稀疏结帐'）？ [英] How to checkout only one file from git repository ('sparse checkout')?

问题描述

>

• 你可以使用git archive（参见 Jared Forsyth 的答案和 Robert Knight 的回答），因为 git1.7.9.5（2012年3月）：

    git archive --remote = git：//git.foo.com/project.git HEAD：path / to / directory filename | tar -x 
    

这将从当前目录的远程仓库的 HEAD 中保存一份'文件名'的副本。

：path / to / directory 部分是可选的。如果排除，则获取的文件将被保存到<当前工作目录> /路径/目录/文件名。

  git archive --format 
 
 = tar --remote = origin HEAD  - < file> | tar xf  -  
  

它类似于 Paul Brannan 的回答：

  git archive --format = tar --remote = origin HEAD：path / to / directory  -  filename | tar -O -xf  -  
  

As 评论由 Doron Gold ，为了 git archive --remote = xxx 才能正常工作，您必须首先在git服务器上的存储库目录中运行此目录（git守护程序在其中运行） ：

  git config daemon.uploadarch true 
  

请参阅 patthoyts '2009年的评论 JakubNarębski在 git：Retrieve

如果您拥有裸仓库的本地副本，您可以执行以下操作，如th是答案，

  git  - 无页面 -  git-dir / path / to / bar / repo .git show branch：path / to / file> file

• 在工作树中.git回购


• 。
  

但是，您可以执行 稀疏结帐 （如果您使用的是Git1.7 +），那么：
$ b

• 启用稀疏结帐选项（ git config core.sparsecheckout true ）
  
• 在 .git / info / sparse-checkout中添加要查看的内容
code> file

• 重新读取工作树以仅显示您需要的内容
  





重新读取工作树：



  $ git read- tree -m -u HEAD 
  

这样，你最终会得到一个工作树，包括你想要的东西（即使它只有一个文件）。




How do I checkout just one file from a git repo?

解决方案

As mentioned in the other answers:

• you can use git archive (see Jared Forsyth's answer and Robert Knight's answer), since git1.7.9.5 (March 2012):

  git archive --remote=git://git.foo.com/project.git HEAD:path/to/directory filename | tar -x
  

That will save a copy of 'filename' from the HEAD of the remote repository in the current directory.

The :path/to/directory part is optional. If excluded, the fetched file will be saved to <current working dir>/path/to/directory/filename.

Fizer Khan mentions below specifying the tar format explicitly:

git archive --format=tar --remote=origin HEAD -- <file> | tar xf -

It is similar to Paul Brannan's answer:

git archive --format=tar --remote=origin HEAD:path/to/directory -- filename | tar -O -xf -

As commented by Doron Gold, for git archive --remote=xxx to work, you MUST first run this inside the directory of your repository on your git server (where git daemon runs):

git config daemon.uploadarch true

See patthoyts' comment of 2009 Jakub Narębski's answer on "git: Retrieve a single file from a repository".

You could alternatively do the following if you have a local copy of the bare repository as mentioned in this answer,

git --no-pager --git-dir /path/to/bar/repo.git show branch:path/to/file >file

---

• or you must clone first the repo, meaning you get the full history:

  • in the .git repo
  • in the working tree.

• But then you can do a sparse checkout (if you are using Git1.7+),:

  • enable the sparse checkout option (git config core.sparsecheckout true)
  • adding what you want to see in the .git/info/sparse-checkout file
  • re-reading the working tree to only display what you need

To re-read the working tree:

$ git read-tree -m -u HEAD

That way, you end up with a working tree including precisely what you want (even if it is only one file)
