Understanding the Linux Directory Structure
Linux File System Hierarchy
The Linux file system is organized in a hierarchical tree-like structure, with a single root directory (/) at the top. Every file and directory resides under this root.
Do You Know?
Understanding the Linux directory structure is crucial for efficient system administration and troubleshooting.
Key Directories
/home Directory
The /home directory is where user accounts' home directories reside. Each user gets their own subdirectory under /home, containing their personal files, configuration, etc.
ls /home/var Directory
The /var directory stores variable data files, such as log files, database files, and spool directories. Its contents are frequently updated.
Important Note:
Never directly modify files in /var without proper understanding. Incorrect changes could lead to system instability.
cd /var; ls -l/etc Directory
The /etc directory contains configuration files for various system programs and services. This is a critical directory.
Avoid This:
Avoid making direct changes to files in /etc unless you are absolutely certain of the implications.
ls /etc/bin Directory
The /bin directory contains essential binary executable files that are needed for basic system operation. These are core commands.
ls /binSummary
- Linux uses a hierarchical file system rooted at /.
- /home stores user data.
- /var stores variable data like logs.
- /etc holds crucial system configuration files.
- /bin contains essential executable files.
