下面是我为单个子目录稀疏签出用例编写的shell脚本

co子目录.sh

localRepo=$1
remoteRepo=$2
subDir=$3


# Create local repository for subdirectory checkout, make it hidden to avoid having to drill down to the subfolder
mkdir ./.$localRepo
cd ./.$localRepo
git init
git remote add -f origin $remoteRepo
git config core.sparseCheckout true

# Add the subdirectory of interest to the sparse checkout.
echo $subDir >> .git/info/sparse-checkout

git pull origin master

# Create convenience symlink to the subdirectory of interest
cd ..
ln -s ./.$localRepo/$subDir $localRepo

编辑：从Git 2.19开始，这终于是可能的，从这个答案中可以看出。

考虑对这个答案投赞成票。

注意：在Git2.19中，只实现了客户端支持，服务器端支持仍然缺失，因此它只在克隆本地存储库时有效。还要注意，大型Git宿主（例如GitHub）实际上并不使用Git服务器，而是使用自己的实现，因此即使Git服务器中显示了支持，也不会自动表示它在Git宿主上运行。（OTOH，因为他们不使用Git服务器，所以在Git服务器出现之前，他们可以在自己的实现中更快地实现它。）

不，这在Git中是不可能的。

在Git中实现这样的东西将是一项巨大的努力，这意味着客户端存储库的完整性将无法再得到保证。如果您感兴趣，请在gitmailinglist上搜索有关“稀疏克隆”和“稀疏获取”的讨论。

一般来说，Git社区的共识是，如果您有几个目录总是独立检出，那么这是两个不同的项目，应该存在于两个不同存储库中。您可以使用Git子模块将它们粘在一起。

git init <repo>
cd <repo>
git remote add origin <url>
git config core.sparsecheckout true
echo "<path you want to clone>/*" >> .git/info/sparse-checkout
git pull --depth=1 origin <branch you want to fetch>

仅从此回购中克隆Jetsurvey文件夹的示例

git init MyFolder
cd MyFolder 
git remote add origin git@github.com:android/compose-samples.git
git config core.sparsecheckout true
echo "Jetsurvey/*" >> .git/info/sparse-checkout
git pull --depth=1 origin main

虽然我讨厌在处理git repos时使用svn：/我一直使用这个；

function git-scp() (
  URL="$1" && shift 1
  svn export ${URL/blob\/master/trunk}
)

这允许您无需修改即可从github url中复制。用法

--- /tmp » git-scp https://github.com/dgraph-io/dgraph/blob/master/contrib/config/kubernetes/helm                                                                                                                  1 ↵

我写了一个从GitHub下载子目录的脚本。

用法：

python get_git_sub_dir.py path/to/sub/dir <RECURSIVE>

上面有很多好的想法和脚本。我情不自禁地将它们组合成一个bash脚本，并提供帮助和错误检查：

#!/bin/bash

function help {
  printf "$1
Clones a specific directory from the master branch of a git repository.

Syntax:
  $(basename $0) [--delrepo] repoUrl sourceDirectory [targetDirectory]

If targetDirectory is not specified it will be set to sourceDirectory.
Downloads a sourceDirectory from a Git repository into targetdirectory.
If targetDirectory is not specified, a directory named after `basename sourceDirectory`
will be created under the current directory.

If --delrepo is specified then the .git subdirectory in the clone will be removed after cloning.


Example 1:
Clone the tree/master/django/conf/app_template directory from the master branch of
git@github.com:django/django.git into ./app_template:

\$ $(basename $0) git@github.com:django/django.git django/conf/app_template

\$ ls app_template/django/conf/app_template/
__init__.py-tpl  admin.py-tpl  apps.py-tpl  migrations  models.py-tpl  tests.py-tpl  views.py-tpl


Example 2:
Clone the django/conf/app_template directory from the master branch of
https://github.com/django/django/tree/master/django/conf/app_template into ~/test:

\$ $(basename $0) git@github.com:django/django.git django/conf/app_template ~/test

\$ ls test/django/conf/app_template/
__init__.py-tpl  admin.py-tpl  apps.py-tpl  migrations  models.py-tpl  tests.py-tpl  views.py-tpl
