檢視 commit id

首先用 git log 檢視版本庫日誌，找出需要匯出的 commit id

$ git log --pretty=oneline

找出差異檔案

使用 git diff 命令可以檢視提交之間的外掛，使用 --name-only 引數只顯示檔名

$ 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

輸出結果就是所有的差異檔案，下面再使用 xargs 將檔案進行下一步處理

將差異檔案打包

$ 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

這樣，../update.tar.gz 檔案就有所有更新的檔案

直接複製出差異檔案

$ 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

xargs -t -i{} cp --parents {} ../update 的引數說明

• -t：顯示執行的命令
• -i{}：將前面的輸入作為一個佔位符 {} 在後面使用
