Introduction to the linux file system
The Linux file system is hierarchical and organized into a tree-like directory structure. Understanding this structure is crucial for effectively navigating and managing files in Linux. This article further explores the significance of specific directories in the Linux file system.
TL;DR
This guide takes you through the key directories in the Linux file system such as /, /home, /root, /etc, explaining their functions and importance. For a foundational understanding, you may refer to our article on Understanding the Linux File System Structure.
Key Directories Explained
/ (Root Directory)
The root directory is the top level of the file system hierarchy. All other directories branch from this root.
/bin
Contains essential command binaries required to boot or repair the system.
/home
Home directories for regular users are stored here. For example, /home/purevoltage would be a user’s personal space.
/root
The root user’s home directory. This is separate from other users’ directories to maintain security.
/etc
Stores system-wide configuration files and shell scripts.
/var
Contains variable data files such as logs and databases.
/usr
Holds binaries, libraries, documentation, and source-code for second level programs.
/tmp
Temporary space used by the system and users.
/boot
Contains the files needed to boot the system.
Navigating Directories
Use the cd command to change directories. For example:
cd /home/purevoltage
