If you are a sysadmin, managing your Linux server\u2019s hard disk partition is a critical task.<\/p>\n

In this tutorial, we\u2019ll focus on how to use sfdisk command-line utility to manage your hard disk partitions.<\/p>\n

While sfdisk is similar to fdisk<\/a>, there are few partition manipulation activities that are very easy to perform in sfdisk. For example, you can create new partitions in an non-interactive method using sfdisk.<\/p>\n

The following sfdisk activities are covered in this tutorial:
\n<\/span><\/p>\n

    \n
  1. View Existing Disk Partitions<\/li>\n
  2. Change Display Units (Display Size in MB)<\/li>\n
  3. Create New Disk Partitions (Interactive Method)<\/li>\n
  4. Verify Partition Table Consistency<\/li>\n
  5. Display Total Partition Size<\/li>\n
  6. Dump Disk Partition Details to Text File<\/li>\n
  7. Create New Partitions from Text File (Non-interactive Method)<\/li>\n
  8. Display Extended Partition Details<\/li>\n
  9. Display Disk Geometry for Debugging<\/li>\n
  10. Display All Disk Partition types<\/li>\n
  11. Manipulate Only a Single Disk Partition<\/li>\n
  12. Dry-run Mode for Verification<\/li>\n
  13. Mark a Specific Partition as Bootable<\/li>\n
  14. Change Partition Type<\/li>\n
  15. Create New Partitions from Shell Script (Non-interactive Method)<\/li>\n<\/ol>\n

    View Existing Disk Partitions<\/h2>\n

    Using -l option you can view all your disk partitions. -l stands for list.<\/p>\n

    By default this will display partitions of all the disks on your systems.<\/p>\n
