问题描述

如何从git存储库中仅检出一个文件?

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

推荐答案

最初，我在2012年提到过 git archive (请参见 Jared Forsyth 的answer 和罗伯特·奈特的答案)，因为 Paul Brannan 的 answer :

Originally, I mentioned in 2012 git archive (see Jared Forsyth's answer and Robert Knight's answer), since git1.7.9.5 (March 2012), Paul Brannan's answer:

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

但是:在2013年，对于远程https://github.com URL ，不再可能.
> 参见旧页面"

But: in 2013, that was no longer possible for remote https://github.com URLs.
See the old page "Can I archive a repository?"

当前(2018年)页面"关于存档GitHub上的内容和数据"建议使用第三方服务，例如 GHTorrent 或

The current (2018) page "About archiving content and data on GitHub" recommends using third-party services like GHTorrent or GH Archive.

因此，您还可以处理本地副本/克隆:

So you can also deal with local copies/clone:

如果您具有此答案，

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

---

或者您必须先克隆该存储库，这意味着您可以获得完整的历史记录: -在.git仓库中 -在工作树中.

---

Or you must clone first the repo, meaning you get the full history: - in the .git repo - in the working tree.

• 但是然后您可以执行 稀疏签出 (如果您使用的是Git1.7 +)，则:
  • 启用稀疏签出选项(git config core.sparsecheckout true)
  • 添加要在.git/info/sparse-checkout文件中看到的内容
  • 重新读取工作树以仅显示您需要的内容
  • 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

    要重新阅读工作树:

    $ git read-tree -m -u HEAD
    

    这样，您最终会得到一棵工作树，其中包括您想要的树(即使它只是一个文件)

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

    Richard Gomes 点(

    一个bash函数，避免下载历史记录，它检索单个分支，并检索所需文件或目录的列表.

    A bash function which avoids downloading the history, which retrieves a single branch and which retrieves a list of files or directories you need.
