I have Ubuntu Server 12.04 running in a VM. /dev/sda1 is mounted on / and is running out of free space. I've already resized the disk in VMware to a much larger size, but I'm having some trouble figuring out how to resize the partition. In Windows, I'd just go to disk management and extend the partition into the free space on the disk. I'm just not sure how to do that via command line in Linux. Can anyone help?
