How to install gpart on Ubuntu

gpart is a tool used for recovering lost or deleted partitions on hard drives. It scans the drive for existing filesystems and identifies the boundaries of partitions. This utility is essential for data recovery when the partition table is corrupted or missing.

In Ubuntu, gpart is not installed by default, but it can be added through the apt package manager. Installing gpart requires updating the package list and downloading the latest version from the repository. This process ensures that you have the necessary components to use gpart effectively.

Once gpart is installed, it operates through the command line. You can configure various scan parameters to optimize the recovery process for your specific needs. These options make gpart a flexible tool for managing partition recovery tasks.
