The ext2, ext3 and ext4 filesystems are some of the most known and used filesystems specifically designed for Linux. The first one, ext2 (second extended filesystems) is, as its name suggests, the older of the three. It has no journal feature, which is the biggest advantage of its successor over him: ext3. Released in 2008, ext4 is the more recent, and currently the default filesystem on many Linux distributions.
SQLite Linux Tutorial for Beginners

mount command in Linux with examples
We can use the mount command in Linux to attach file systems and removable devices such as USB flash drives. The default file system for most Linux distributions is ext4. We can also dismount file systems with the unmount command.
dd command in Linux with examples
Linux considers anything stored on a file system as files, even block devices. This means commands such as the dd command in Linux can be very handy in many situations, as it can be used to convert and copy files in the terminal, backup disks, or wipe data. The dd command is just as fundamental as it is useful, as it’s ready to use even on the most basic installations of Linux distros.
du command in Linux with examples
On any operating system, the files on your hard disk take up a certain amount of space. In Linux specifically, you can view how much space that these files take up in the command line terminal by using the du command. The du command (the name is shortened from “disk usage”), as the name implies, will simply display, in its output, the amount of disk space being used by a specified file or directory.
