Editor to share with you what file .d in linux refers to, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Linux in the ".d" file means: 1, dependent file, where d is the meaning of dependence; 2, the default configuration file, in which d is the meaning of default; 3, the dynamic meaning of the file, where d is the meaning of Dynamic.

The operating environment of this tutorial: linux7.3 system, Dell G3 computer.

What is the .d file in linux

Dependent files: dependence

.d may also mean default, indicating the default (configuration) file

It is also possible that it means Dynamic, a document that represents dynamic meaning.

Folders with .d are more common, such as many under / etc, indicating that there are system default configuration files under the folder.

Generally, in order to maintain the compatibility with the original configuration, the .d ending directory is added.

Such as: / etc/X11/xorg.conf this is originally a file, and now there is a directory like / etc/X11/xorg.conf.d. The relevant settings of the video card driver were originally placed in the file / etc/X11/xorg.conf. Now, for the sake of the simplicity and flexibility of the configuration file, you can allocate the configuration according to the situation and throw it into / etc/X11/xorg.conf.d. Add it in the same way as the rules. The system will automatically go to this / etc/X11/xorg.conf.d to find these rules and set them according to the rules. This maintains compatibility with the previous / etc/X11/xorg.conf method.

Another example: in the Yum distribution, / etc/yum.repo is the configuration file of yum, so you can throw all the yum sources into the yum.repo file, and now you can also throw different source configuration files into / etc/yum.repo.d, and only set some common configuration options in yum.repo. In this way, which source you don't want can be deleted from / etc/yum.repo.d without affecting other sources, and it's the same reason to add more sources.

And / etc/env.d,/etc/profile.d,/etc/udev.rules.d, etc. It's all the same.
