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 read some other posts about the cd not ejecting and they didn't seem to help me. My cdrom works fine and everything, but when its not in use, I can't eject it. It says:
umount: /mnt/cdrom: device is busy
eject: unmount of `/dev/cdrom' failed
and nothings busy! I can't eject the cd with the button on the player either. If you can help at all I apreciate it. Thanks.
i was logged in as root (i know, i know...), and i was trying to isntall a package from the fedora cd #1. it couldnt read the cd (yes, it was dirt- and scratch-free), and when i tried to eject it, i got the same error. Only cd it has happened to so far.
i rebooted, but it was still locked. i rebooted again, and ejected while booting fedora.
fuser -m -v /mnt/cdrom
That will tell you what's using the cd. If you just want to kill them all do
fuser -k -m /mnt/cdrom
And they will all be dead This as root of course. After that umount will work just fine.
Nopes, what happens is you have programs that are using the CD.
Unlike windows you can't just remove it, and leave those programs hanging. Partiailly because of how Linux also treats any normal disk drive too, and how it writes to them.
fuser -k -m <drive>
kills all the programs that are using that disk, then it can safely be unmounted.
