Linux directory structure

There is a standard structure for Linux directories. According to Linux, generally, everything is a file, even directories and devices. In order to work properly, Linux manages these files in a specific way under a hierarchical design:

• /root: All the files and directories start from this directory
• /home: Contains personal files of all users
• /bin: Contains all the binaries (executables)
• /sbin: Like /bin, but it contains the system binaries
• /lib: Contains required library files
• /usr: Contains binaries used by a normal user
• /opt: Contains optional add-on applications
• /etc: Contains all the required configuration files for the programs
• /dev: Contains device files
• /media: Contains files of temporary removable devices
• /mnt: Contains mount point for filesystems
• /boot: Contains boot loader files
• /tmp: Contains temporary files
• /var: Contains variable files, such as logs
• /proc: Contains information about the system processes:

There are many types of file in Linux operation systems. Each file is represented by a specific symbol—directories, regular files, and sockets, which are communication techniques between applications.
