Various directories

We will explore the directory structure in Linux so that it will be useful later on:

  • /bin/: This contains commands used by a regular user.
  • /boot/: The files required for the operating system startup are stored here.
  • /cdrom/: When CD-ROM is mounted, the CD-ROM files are accessible here.
  • /dev/: The device driver files are stored in this folder. These device driver files will point to hardware-related programs running in kernel.
  • /etc/: This folder contains configuration files and startup scripts.
  • /home/: This folder contains a home folder of all users except the administrator.
  • /lib/: The library files are stored in this folder.
  • /media/: External media such as a USB pen drive is mounted in this folder.
  • /opt/: The optional packages are installed in this folder.
  • /proc/: This contains files which give information about kernel and every process running in OS.
  • /root/: This is the administrators home folder.
  • /sbin/: This contains commands used by the administrator or root user.
  • /usr/: This contains secondary programs, libraries, and documentation about user-related programs.
  • /var/: This contains variable data such as http, tftp, and similar other.
  • /sys/: This dynamically creates the sys files
