[Q&A]
Q1. What are device files in Linux, and where are they located?
A1. Device files represent hardware devices and are located in the /dev directory.
[PART 5 - /etc]
The /etc directory contains configuration files for system and application settings. Important files like 'passwd', 'hosts', and 'fstab' are located here.
[USE CASE]
- Configure system settings like network configurations or user accounts.
[Q&A]
Q1. Where are system configuration files stored in Linux?
A1. System configuration files are stored in the /etc directory.
[PART 6 - /home]
The /home directory is the default location for user home directories. Each user typically has a subdirectory within /home to store their personal files and configurations.
[USE CASE]
- Access and manage user-specific files and settings.
[Q&A]
Q1. Where are user home directories located in Linux?
A1. User home directories are located in the /home directory.
[PART 7 - /lib and /lib64]
The /lib and /lib64 directories contain shared libraries required by the system and various applications. /lib64 is for 64-bit systems.
[USE CASE]
- Store shared libraries essential for program execution.
[Q&A]
Q1. What is the difference between /lib and /lib64 in Linux?
A1. /lib contains shared libraries for 32-bit systems, while /lib64 is for 64-bit systems.
[PART 8 - /mnt and /media]
The /mnt directory is used for temporary mount points, where external file systems can be mounted. The /media directory serves a similar purpose but is typically used for mounting removable media like USB drives.
[USE CASE]
- Mount external file systems or removable media for data access.
[Q&A]
Q1. How can I mount a USB drive in Linux?
A1. Plug the USB drive and it will automatically mount to /media.
[PART 9 - /opt]
The /opt directory is reserved for optional or third-party software packages. Applications installed here are usually self-contained and not part of the core Linux distribution.
[USE CASE]
- Install third-party applications without interfering with system files.
[Q&A]
Q1. Where should I install optional software packages in Linux?
A1. Optional software packages should be installed in the /opt directory.
[PART 10 - /proc]
The /proc directory is a virtual file system that provides information about the system and running processes. It's not storing actual files but rather offers real-time information accessible as files.
[USE CASE]
- Access system information and process details.
[Q&A]
Q1. What is the purpose of the /proc directory in Linux?
A1. The /proc directory provides real-time system and process information.
[PART 11 - /root]
The /root directory is the home directory for the system's root user (superuser). This user has full administrative privileges on the system.
[USE CASE]
- Administer the system and perform system-level tasks.
[Q&A]
Q1. What is the role of the /root directory in Linux?
A1. The /root directory is the home directory for the root user with administrative privileges.
[PART 12 - /run]
The /run directory contains temporary files representing system state since the last boot. It is often used by applications during runtime.
[USE CASE]
- Store temporary files for system state between reboots.
[Q&A]
Q1. What type of data is stored in the /run directory?
A1. The /run directory contains temporary files representing system state since the last boot.
[PART 13 - /sbin]
The /sbin directory holds system binaries that are primarily used by the system administrator. These executables typically require elevated privileges to run.
[USE CASE]
- Execute system administration commands.
[Q&A]
Q1. Where are system administration commands located in Linux?
A1. System administration commands are located in the /sbin directory.
[PART 14 - /srv]
The /srv directory is used for site-specific data, such as web server content or data shared among users.
[USE CASE]
- Store data for site-specific services or applications.
[Q&A]
Q1. What is the purpose of the /srv directory in Linux?
A1. The /srv directory is used to store site-specific data, such as web server content.
[PART 15 - /sys]
The /sys directory provides a virtual file system that exposes kernel attributes and information.
[USE CASE]
- Access and modify kernel attributes and information.
[Q&A]
Q1. What kind of data is accessible through the /sys directory?
A1. The /sys directory provides kernel attributes and information.
[PART 16 - /tmp]
The /tmp directory provides a space for temporary files that are needed during the system's operation. It's common for applications to use /tmp for short-term storage.

The Linux File System Hierarchy is a structured organization of directories and files in a Linux system. At the top level is the root directory ("/"), which serves as the starting point for the entire file system. Key directories include /bin and /sbin, which contain essential system binaries, /etc for configuration files, and /home for user home directories. The /var directory holds variable data, such as logs and temporary files, while /dev contains device files for hardware communication.
