Understanding the Linux Directory Structure

understanding the linux directory structure

In this blog post, we are going to explain the Linux Directory Structure and how everything is connected in Linux operating system.

Linux is a very complex system and requires an efficient way to start, stop and maintain the system. Everything in Linux is a file, and even the directories count as files. There are three types of files in the Linux system: general files, directory files, and device files.

In the next paragraphs, we are going to explain the types of files and the most important directories such as root, bin, cdrom, boot, dev, etc, home, lib, mnt, tmp and many more. Let’s get started!

Root Directory

This is the main root/directory, and everything in Linux is located in this directory. It contains all directories and subdirectories on the Linux file system. You should know that in Linux everything starts with the root/directory, and this directory is different than the home root directory /root.

Bin Directory

The /bin directory contains the binary files, also known as user-essential binary programs. Most of the bin files are executable files and these files are important for the system.

CDRom

Even though this directory is not standard for the Filesystem Hierarchy, we can still find it in the Linux operating systems. This directory is for the temporarily inserted CD-ROMs on any Linux Operating system.

The Boot directory

The /boot directory contains the static boot files and folders such as grub, etc., conf. Besides these files, the /boot directory contains the Kernel files and is the most important directory in the Linux system.

The dev directory

The /dev directory contains the device files such as the vda, sda and etc. These files are most commonly known as the attached files on the system such as keyboard, hard drive, USB drive and etc.

The etc directory

The /etc directory contains the system configuration files editable with a text editor. This directory also contains user-specific configuration files.

Home Directory

The /home directory contains the home directory for each user created on the system. The home directory contains the users’ data files and some configuration files. The users are locked in their home directory and only have privileges to write into the /home/user directory on the server.

The lib directory

The /lib directory contains the essential shared library files that are necessary for the /bin directory.

The mnt directory

The /mnt directory contains the mounted temporary file systems. It can be used as a temporary mount directory for Hard Disks, USB drives, and CD-ROMs

The tmp directory

The last directory that will be described in this blog post is the /tmp directory. The temporary directory is used for the temporary application files that will be deleted on the system reboot. Also, you can delete all files from the /tmp directory anytime you want.
