The Linux File System in 4 Minutes | A MUST Learn
In a standard Linux file system hierarchy, the directories you mentioned are organized according to the Filesystem Hierarchy Standard (FHS). Here's a brief overview of each directory in the context of a standard Linux system:
The top-level directory, containing all other directories and files.
Essential command binaries required for system boot and recovery.
System administration binaries, often used by the system administrator.
/usr (Unix System Resources):
Contains user utilities and applications, organized into subdirectories like /usr/bin for user binaries and /usr/sbin for system administration binaries.
/opt (Optional Software):
Directory for optional or third-party software.
/etc (Configuration Files):
Configuration files and shell scripts used to configure the system and applications.
/home (Home Directories):
Home directories for regular users.
/boot (Boot Loader Files):
Files required for the boot process, including the kernel and bootloader configuration.
Shared libraries needed by the system and applications.
/root (Root User Home Directory):
Home directory for the root user.
Directory for temporary files, typically cleared on system reboot.
Variable files that change as the system runs, such as logs, spool files, and temporary files.
Device files representing physical and virtual devices.
/media and /mnt (Mount Points):
Directories used as mount points for removable media or temporarily mounted filesystems.
These directories provide a standardized structure, making it easier for users and administrators to locate and manage files and resources on a Linux system. Keep in mind that specific distributions might have additional directories or variations, but the FHS serves as a common guideline for organizing the file system in Unix-like operating systems.
