Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have had good success reducing the swap file thusly:
0. BACKUP your data:
- I like to boot from a live cd, and then dd the entire drive over to another one.
1. Make sure you have sufficient physical memory to hold the swap file contents, and then
turn the swap off with something like:
- swapoff -Lswap (substitute your values)
- swapon -s (status check to be sure that it worked)
- (if status check reveals a swap line-item, then you specified incorrect swap label.
2. Run fdisk and:
- List partitions with "p" command
- Delete the partition that is home for your swap file with "d" command
- Create a smaller Linux-Swap partition with "n" command
- Make sure it is a Linux-Swap partition (type 82) (Change with "t" command)
- Create a new Linux partition for new file system in rescued space ("n" and "t" commands)
- Write partition table with "w" command
3. The new table won't be used until the next reboot.
4. After reboot, make sure your swap is made and turned on.
- mkswap /dev/hda4 -Lswap (substitute your values)
- swapon -Lswap
- swapon -s (check to make sure swap is turned on)
5. Create a mount point for your new file system partition (mkdir ...)
6. Make the new file system in the new partition:
- mkfs /dev/hda2 (or whatever partition it happens to be)
7. Mount the new fs and enjoy:
- mount /dev/hda2 /newmountpoint...
Note the extreme importance of syncing and turning
the swap off before you change any partitions.
- FAILURE_TO_DO_THIS = LOST_DATA!
This works for me, but your mileage may vary. Use at your own risk!
