致“更干净”的历史记录，尽管有些正统主义者可能认为最好的方法是再提交一次（而不
是使用
--amend
）。
哪种方法最好？这基本上视用户而定，不过其中也存在一些注意事项。如果通过
Git
和共
享仓库与他人协作，那么使用
--amend
改写已发送到共享仓库的提交通常不是什么好主意。
一个例外是在使用
Gerrit
的环境中广泛应用改写提交
。第

变更并提交已跟踪的文件
你已经创建好了仓库，添加了一些新文件并向仓库提交了变更。现在，需要对仓库中的文
件做一些改动。该怎么办？
幸运的是，向仓库提交文件修正版的步骤基本上和先前演示过的一样。
1.
修改工作目录中的文件。
2.
使用
git add
将变更暂存至索引。这使得索引与工作目录处于同步状态。
3.
使用
git commit
提交变更。这不仅使得仓库与索引处于同步状态，还创建了指向仓库
状态的时间点引用。
来详细回顾一下操作过程。假设由于交换机配置发生了变化（也可能是因为你强制要求配
置只有在被检入源代码控制之后才能部署），需要修改文件
sw1.txt
。修改过被跟踪的文件
（
Git
已经知晓且正在跟踪的文件）之后，
git status
会显示存在变更。
