Fast way to inspect disks partitions and mount points from the command line. 06.04.2026 | reading time: 2 min On a Linux system knowing what block devices exist is essential, and `lsblk` is the quickest way to inspect disks partitions loop devices sizes types and mount points so he can understand the storage layout at a glance. Discover with one command Run a simple listing to see devices and mounts then inspect results, for example execute ```$ lsblk -o NAME,SIZE,TYPE,MOUNTPOINT``` and expect output similar to ```NAME SIZE TYPE MOUNTPOINT sda 477G disk ├─sda1 512M part /boot └─sda2 476.5G part /``` which shows device names sizes types and where they are mounted. Deeper options to try Show filesystem info and UUIDs with `lsblk -f` print full device paths with `lsblk -p` get JSON for scripts with `lsblk -J` and customize columns using `lsblk -o` so he can combine those options to get exactly the view he needs. When lsblk meets other tools Correlate `lsblk` output with `blkid` to read UUIDs with labels use `fdisk -l` or `parted -l` for partition table details and check mounts with `mount` or `findmnt` to complete the picture when troubleshooting or preparing a drive for imaging. Wrap up and next steps Mastering `lsblk` is a small but essential step toward storage administration so practice on a lab machine and consider advancing with certification such as CompTIA Linux+ or LPIC-1 and intensive exam preparation at bitsandbytes.academy.
