/ – The Root Directory
/bin – Binaries
- The ‘/bin’ directly contains the executable files of many basic shell commands like ls, cp, cd etc. Mostly the programs are in binary format here and accessible by all the users in the Linux system.
/dev – Device Files
- This directory only contains special files, including those relating to the devices. These are virtual files, not physically on the disk. Some interesting examples of these files are: 1. /dev/null: can be sent to destroy any file or string 2. /dev/zero: contains an infinite sequence of 0 3. /dev/random: contains an infinite sequence of random values
/etc – Configuration Files
- The /etc directory contains the core configuration files of the system, use primarily by the administrator and services, such as the password file and networking files. If you need to make changes in system configuration (for example changing the hostname), this is where you’ll find the respective files.
/usr – User Binaries and Program Data
- in ‘/usr’ go all the executable files, libraries, source of most of the system programs. For this reason, most of the files contained therein is readonly (for the normal user) 1. ‘/usr/bin’ contains basic user commands 2. ‘/usr/sbin’ contains additional commands for the administrator 3. ‘/usr/lib’ contains the system libraries 4. ‘/usr/share’ contains documentation or common to all libraries, f…

Suppose your Linux system has two users, Alice and Bob. …
/lib – Shared Libraries
- Libraries are basically codes that can be used by the executable binaries. The /lib directory holds the libraries needed by the binaries in /bin and /sbin directories. Libraries needed by the binaries in the /usr/bin and /usr/sbin are located in the directory /usr/lib.
/sbin – System Binaries
- This is similar to the /bin directory. The only difference is that is contains the binaries that can only be run by root or a sudo user. You can think of the ‘s’ in ‘sbin’ as super or sudo.
/tmp – Temporary Files
- As the name suggests, this directory holds temporary files. Many applications use this directory to store temporary files. Even you can use directory to store temporary files. But do note that the contains of the /tmp directories are deleted when your system restarts. Some Linux system also delete files old files automatically so don’ store anything important here.
/var – Variable Data Files
- Var, short for variable, is where programs store runtime information like system logging, user tracking, caches, and other files that system programs create and manage. The files stored here are NOT cleaned automatically and hence it provides a good place for system administrators to look for information about their system behavior. For example, if you want to check the login his…
