fdisk and lsblk in Linux CLI - Mini Project: Build & Apply

Using fdisk and lsblk to List and Identify Disk Partitions

📖 Scenario: You are managing a Linux system and want to see the details of your disk drives and their partitions. You will use two common commands: fdisk and lsblk. These commands help you understand how your disks are divided and what partitions exist.

🎯 Goal: Learn how to use fdisk to list disk partitions and lsblk to display block devices in a tree format. You will write simple commands to view this information and understand the output.

📋 What You'll Learn

Use the fdisk command with the -l option to list all disk partitions

Use the lsblk command to display block devices in a tree view

Understand how to read the output of both commands

💡 Why This Matters

🌍 Real World

System administrators often need to check disk partitions and usage to manage storage and troubleshoot issues.

💼 Career

Knowing how to use <code>fdisk</code> and <code>lsblk</code> is essential for Linux system administration and automation tasks.

1

List all disk partitions using fdisk

Type the command sudo fdisk -l to list all disk partitions on your system.

Linux CLI

# Type the command to list all disk partitions
# Your code here

Need a hint?

The fdisk command with -l lists all partitions. You need sudo to run it with the right permissions.

2

Display block devices using lsblk

Type the command lsblk to show all block devices and their partitions in a tree format.

Linux CLI

sudo fdisk -l
# Type the command to display block devices
# Your code here

Need a hint?

The lsblk command shows disks and partitions in a clear tree view.

3

Filter fdisk output for a specific disk

Use the command sudo fdisk -l /dev/sda to list partitions only for the disk /dev/sda.

Linux CLI

sudo fdisk -l
lsblk
# Type the command to list partitions for /dev/sda
# Your code here

Need a hint?

Replace /dev/sda with the disk you want to check. This command shows only that disk's partitions.

4

Show detailed lsblk output with sizes and mount points

Type the command lsblk -o NAME,SIZE,MOUNTPOINT to display device names, sizes, and mount points.

Linux CLI

sudo fdisk -l
lsblk
sudo fdisk -l /dev/sda
# Type the command to show detailed lsblk output
# Your code here

Need a hint?

The -o option lets you choose which columns to show. Here, you see device names, sizes, and where they are mounted.
