Mounting CD-ROM in Ubuntu

I'm somewhat forgetful when I don't use a command every day. While trying to remember the exact command here I did a Google search and each answer I found was missing some step. So I am going to write out the exact steps here for anyone getting lost, and also for my self in the future. :)

This is from Ubuntu so your distribution might be slightly different.

1) sudo mkdir /mnt/cdrom

2) sudo mount /dev/cdrom /mnt/cdrom

3) ls /mnt/cdrom

4) Done!

It's really simple but from searching there were lots of very complex answers, and I prefer the simple as possible method.

Enjoy!
