Understanding the Linux File System Hierarchy

In this lesson, you will gain a fundamental understanding of the Linux/Unix file system hierarchy. You will learn how the file system is organized, the key directories that make up this hierarchy, and their significance.

The Linux/Unix File System Hierarchy

Linux and Unix operating systems organize their file systems in a hierarchical structure. This structure starts at the root directory /, which is the highest level of the file system, and extends downward, forming a tree-like structure. Understanding this hierarchy is essential for navigating and managing your system effectively.

File Paths

File paths specify the location of files and directories within the file system hierarchy. They begin with the root directory / and follow the directory structure. For example, the path to a directory might be /path/to/directory.

Key Directories in the File System Hierarchy

Here are important directories and their descriptions in the Linux/Unix file system hierarchy:

1. / (Root Directory): The top-level directory that contains all other directories and files on your system.
2. /bin (Binary Binaries): Contains essential system binary executables required for system maintenance and recovery.
3. /sbin (System Binaries): Houses binaries for system administration and maintenance, often reserved for the superuser (root).
4. /etc (System Configuration): Contains system-wide configuration files and directories.
5. /var (Variable Data): Holds variable data files, such as logs and temporary files, that may change during the course of normal system operation.
6. /tmp (Temporary Directory): A location for temporary files used by applications and users. Files in this directory are typically deleted upon system reboot.
7. /mnt (Mount Point): This directory is used for temporarily mounting external storage devices like USB drives and network shares.
8. **/media (Removable Media Mount P…
