Introduction to Disk Partitioning with fdisk and lsblk

 Introduction

Disk partitioning is the process of dividing a hard drive into sections that the operating system can manage. In Linux, tools like fdisk and lsblk help you view and manage partitions.

Step 1: List All Disks and Partitions

lsblk

➡️ Displays disks, partitions, and mount points in a tree view.

Step 2: Check Disk Information

sudo fdisk -l

➡️ Lists all partitions and their details (size, type, boot flag).

Step 3: Start fdisk on a Disk

sudo fdisk /dev/sda

➡️ Replace /dev/sda with the disk you want to manage.

Step 4: Create a New Partition

Inside fdisk:

Press n → new partition

Choose partition type (primary/extended)

Select start and end sectors

Press w to save changes

Step 5: Format the New Partition

sudo mkfs.ext4 /dev/sdaX

➡️ Replace /dev/sdaX with the partition name.

Step 6: Mount the Partition

sudo mount /dev/sdaX /mnt

➡️ The partition is now accessible under /mnt.

Conclusion

Using lsblk and fdisk, you can manage disk partitions effectively. Next, we’ll cover file search commands like find, locate, and which.
