Hello! I have a /home partition that is almost full, and there is another partition nearby with a lot of free space. I would like to reduce the size of this neighboring partition and add the freed space to /home. I would like to do this safely, without using a Live USB or bootable flash drive. Is this possible?

upd: gparted just worked(through a live usb stick)! Sometimes I try to use symlinks, but not this time :) Thanks everyone!
