Gparted stands for Gnome Partition Editor.

This tool has GUI interface and it is really easy to manage your partitions with it.
It also comes as GPartEd live CD.

I think the live CD is a must-have tool for any Linux administrator.

Gparted can not operate on mounted Partition, that is why the Live CD is more important.

Installation

Debian / Ubuntu

sudo apt-get install gparted
