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 a 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 the 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, are mounted in this folder.
• /opt/: The optional packages are installed in this folder.
• /proc/: This contains files that give information about the kernel and every process running in the OS.
• /root/: This is the administrator's 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, logs, and others.
• /sys/: This dynamically creates the sys files.
