I need to reallocate disk space from my /var partition to my / partition. I don't have Partition Magic handy (and from what I've read, it's not always the best). I'm wondering if what I'm trying to do is possible with fdisk? I've searched the forum and googled, but no dice.

GOAL: move ~800MB from the /var partition to /
INFO:
[root@linuxbox root]# fdisk -l

Disk /dev/hda: 6448 MB, 6448619520 bytes
255 heads, 63 sectors/track, 784 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

[root@linuxbox root]$ df -h

Detailed answers are appreciated as I am a newbie.

parted should do the trick. you can search google.com/linux for details.
what parted can do for you is reduce /dev/hda2 and then extend /dev/hda3 using the resize option.
before you do it, make sure you backup your data.
but being a newbie, i suggest that you just repartition.

Here is a live-cd image that contains the program parted. It is only around 50 Meg in size and contains many tools you could use to backup and change partitions on your hard drive.
It will resize a ext2, ext3 or reiserfs file system. However the start of the partition can't change. You could boot up with this disk ( your / and /var partitions won't be mounted then ) and back up the /var partition, delete /var, resize / , create a new /var, and restore /var.

Luckily, your /var partition is situated just after your / partition.
