本文介绍了如何通过git命令查看commit id，找出差异文件，并将其打包或直接复制出来。通过`git log`获取commit id，使用`git diff --name-only <commit1> <commit2>`显示差异文件名，利用`git archive`将差异文件打包成update.tar.gz，或者使用`git checkout -p <commit>`直接复制出差异文件。

查看 commit id

首先用 git log 查看版本库日志，找出需要导出的 commit id

$ git log --pretty=oneline

找出差异文件

使用 git diff 命令可以查看提交之间的插件，使用 --name-only 参数只显示文件名

$ git diff 456bcb 93593a --name-only
public/js/index.js
resources/views/index.blade.php
resources/views/public/pagination.blade.php
resources/views/search.blade.php
resources/views/vendor/pagination/bootstrap-4.blade.php
resources/views/vendor/pagination/default.blade.php
resources/views/vendor/pagination/semantic-ui.blade.php
resources/views/vendor/pagination/simple-bootstrap-4.blade.php
resources/views/vendor/pagination/simple-default.blade.php

输出结果就是所有的差异文件，下面再使用 xargs 将文件进行下一步处理

将差异文件打包

$ git diff 456bcb 93593a --name-only | xargs tar -czvf ../update.tar.gz
public/js/index.js
resources/views/index.blade.php
resources/views/public/pagination.blade.php
resources/views/search.blade.php
resources/views/vendor/pagination/bootstrap-4.blade.php
resources/views/vendor/pagination/default.blade.php
resources/views/vendor/pagination/semantic-ui.blade.php
resources/views/vendor/pagination/simple-bootstrap-4.blade.php
resources/views/vendor/pagination/simple-default.blade.php

这样，../update.tar.gz 文件就有所有更新的文件

直接复制出差异文件

$ git diff 456bcb 93593a --name-only | xargs -t -i{} cp --parents {} ../update
cp --parents public/js/index.js ../update
cp --parents resources/views/index.blade.php ../update
cp --parents resources/views/public/pagination.blade.php ../update
cp --parents resources/views/search.blade.php ../update
cp --parents resources/views/vendor/pagination/bootstrap-4.blade.php ../update
cp --parents resources/views/vendor/pagination/default.blade.php ../update
cp --parents resources/views/vendor/pagination/semantic-ui.blade.php ../update
cp --parents resources/views/vendor/pagination/simple-bootstrap-4.blade.php ../update
cp --parents resources/views/vendor/pagination/simple-default.blade.php ../update
