Linux systems provide many ways to look at disk partitions. In this post, we’ll look at a series of commands, each which shows useful information but in a different format and with a different focus. Maybe one will make your favorites list.
One of the most useful commands is the lsblk (list block devices) command that provides a very nicely formatted display of block devices and disk partitions. In the example below, we can see that the system has two disks (sda and sdb) and that sdb has both a very small (500M) partition and a large one (465.3G). Disks and partitions (part) are clearly labelled and the relationship between the disks and partitions is quite obvious. We also see that the system has a cdrom (sr0).
