Git是否可以忽略对已经commit过的文件的变更？

Question

比如config.yml我已经commit了。 然后修改了config.yml，但对此文件的修改不希望再commit。

Answer 1

To ignore all changes

git reset --hard

If you just ignore a single file

git checkout filename.txt

---

sry, I misinterpreted it

You can omit the config.yml.example 加入版本库，然后将 config.yml 在 .gitignore.

When configuration is enabled, cp config.yml.example config.yml 即可，然后对于 config.yml updates will not be committed.

Answer 2

Just put it directly in .gitignore 文件里面屏蔽掉 config.yml. What has been committed before will not change, and Git will automatically ignore the modification to this file in the future.
