Linux 中 .d 后缀表示什么呢？

[CongratulateWE]

Linux 中有很多 .d 结尾的文件夹，比如最常见的 /etc/nginx/conf.d、/etc/sudoers.d 等等。

这个 d 是什么意思呢？

[CongratulateWE]

"d" stands for directory and such a directory is a collection of configuration files which are often fragments that are included in the main configuration file. The point is to compartmentalize configuration concerns to increase maintainability.

"d" 代表文件夹 directory，这个文件夹里是一个配置的集合，会被 include 到主配置文件里。重点是划分配置关注点以提高可维护性。
