Introduction to Linux File System
The Linux file system is the structure in which files are organized and stored on a Linux-based operating system. It is hierarchical in nature, starting with the root directory (“/”) and branching out into subdirectories.
Each directory can contain files and additional subdirectories, creating a tree-like structure. Understanding the Linux file system is essential for navigating and managing files effectively on a Linux system.
Key directories in the Linux file system include /bin (containing essential binary executables), /etc (configuration files), and /home (user directories).
By familiarizing yourself with the Linux file system, you can become more proficient in using and administering Linux systems.
