DIRECTORY STRUCTURE OF LINUX

 

 Directory is a hierarchy for set a file or folder. After installing linux, so we have see a standard directory. For example, in drive C: of Windows have Program Files folder which for installed application  in there or Driver folder which we can see what driver is already installed.

OK, lets check this out for Directory structure in Linux.

1. /bin : All the executable binary programs (file) required during booting, repairing, files required to run into single-user-mode, and other important, basic commands viz., cat, du, df, tar, rpm, wc, history, etc.
    
2. /boot : Holds important files during boot-up process, including Linux Kernel.
    
3. /dev : Contains device files for all the hardware devices on the machine e.g., cdrom, cpu, etc
    
4. /etc : Contains Application’s configuration files, startup, shutdown, start, stop script for every individual program.
    
5. /home : Home directory of the users. Every time a new user is created, a directory in the name of user is created within home directory which contains other directories like Desktop, Downloads, Documents, etc.
    
6. /lib : The Lib directory contains kernel modules and shared library images required to boot the system and run commands in root file system.
    
7. /lost+found : This Directory is installed during installation of Linux, useful for recovering files which may be broken due to unexpected shut-down.
    
8. /media : Temporary mount directory is created for removable devices viz., media/cdrom.
    
9. /mnt : Temporary mount directory for mounting file system.
    
10. /opt : Optional is abbreviated as opt. Contains third party application software. Viz., Java, etc.
     
11. /proc : A virtual and pseudo file-system which contains information about running process with a particular Process-id aka pid.
     
12. /root : This is the home directory of root user and should never be confused with ‘/‘
     
13. /run : This directory is the only clean solution for early-runtime-dir problem.
     
14. /sbin : Contains binary executable programs, required by System Administrator, for Maintenance. Viz., iptables, fdisk, ifconfig, swapon, reboot, etc.
     
15. /srv : Service is abbreviated as ‘srv‘. This directory contains server specific and service related files.
     
16. /sys : Modern Linux distributions include a /sys directory as a virtual filesystem, which stores and allows modification of the devices connected to the system.
     
17. /tmp :System’s Temporary Directory, Accessible by users and root. Stores temporary files for user and system, till next boot.
     
18. /usr : Contains executable binaries, documentation, source code, libraries for second level program.
     
19. /var : Stands for variable. The contents of this file is expected to grow. This directory contains log, lock, spool, mail and temp files.

Thats all about Directory Structure of Linux, Im sorry if my grammar is worst :D
