A Quick and Easy Guide to Listing Available Partitions on Linux

fdisk is a Linux command-line tool used to manage disk partitions. One of the most commonly used options in fdisk is “-l” which lists all the available partitions on a Linux system. In this post, we will explain how to use “fdisk -l” to list available partitions on Linux and how it can be useful.

What is “fdisk -l”?

“fdisk -l” is a Linux command-line tool that lists all the available partitions on all disks attached to the system. The command can be run as a superuser or with sudo privileges to display the partition table information in a readable format.

Using “fdisk -l” to list available partitions

To list available partitions on a Linux system, follow these steps:

  1. Open the terminal on your Linux machine.
  2. Type “fdisk -l” and press Enter. The command will display the partition information for each disk attached to the system, including the disk name, size, partition type, start and end sectors, and the file system type used by each partition.
  3. Review the output of the command to identify the device name and partition number for a specific device.

Understanding the output of “fdisk -l”

The output of “fdisk -l” provides important information about the disk partitions on a Linux system. Here are some key pieces of information to look out for:

  • Disk name: The name of the disk attached to the system.
  • Disk size: The size of the disk in bytes, megabytes, or gigabytes.
  • Partition type: The type of partition table used on the disk, such as MBR (Master Boot Record) or GPT (GUID Partition Table).
  • Start and end sectors: The start and end sectors of each partition on the disk.
  • File system type: The file system type used by each partition, such as ext4, NTFS, or FAT32.

Using “fdisk -l” to manage disk partitions

In addition to listing available partitions on Linux, “fdisk -l” can also be used to manage disk partitions. The command can be used to create, delete, or modify partitions on a disk. However, it is important to exercise caution when using fdisk to modify partitions, as any mistakes can result in data loss or corruption.
