如果您从未计划与从中克隆的存储库交互，则可以执行完整的git克隆并使用

git filter-branch --subdirectory-filter <subdirectory>

这样，至少历史会被保存下来。

这看起来简单得多：

git archive --remote=<repo_url> <branch> <path> | tar xvf -

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

"
  exit 1
}

if [ -z "$1" ]; then help "Error: repoUrl was not specified.\n"; fi
if [ -z "$2" ]; then help "Error: sourceDirectory was not specified."; fi

if [ "$1" == --delrepo ]; then
  DEL_REPO=true
  shift
fi

REPO_URL="$1"
SOURCE_DIRECTORY="$2"
if [ "$3" ]; then
  TARGET_DIRECTORY="$3"
else
  TARGET_DIRECTORY="$(basename $2)"
fi

echo "Cloning into $TARGET_DIRECTORY"
mkdir -p "$TARGET_DIRECTORY"
cd "$TARGET_DIRECTORY"
git init
git remote add origin -f "$REPO_URL"
git config core.sparseCheckout true

echo "$SOURCE_DIRECTORY" > .git/info/sparse-checkout
git pull --depth=1 origin master

if [ "$DEL_REPO" ]; then rm -rf .git; fi

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 ↵

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

为了澄清这里的一些好答案，许多答案中概述的步骤假设您在某个地方已经有了远程存储库。

给定：现有的git存储库，例如。git@github.com：some user/fullrepo.git，其中包含一个或多个您希望独立于repo其余部分拉动的目录，例如名为app1和app2的目录

假设您有一个如上所述的git存储库。。。

然后：您可以运行以下步骤，从较大的存储库中仅提取特定目录：

mkdir app1
cd app1
git init
git remote add origin git@github.com:some-user/full-repo.git
git config core.sparsecheckout true
echo "app1/" >> .git/info/sparse-checkout
git pull origin master

我错误地认为必须在原始存储库上设置稀疏签出选项，但事实并非如此：在从远程提取之前，您需要在本地定义所需的目录。远程回购不知道或不关心您只想跟踪回购的一部分。

希望这一澄清对其他人有所帮助。
