Checking if a device is mounted using a script


i would like to write a script which does the following actions:
1. In case the cdrom is mounted, unmount and eject it.
2. In case it isn't mount it.

Now I have these simple questions:
How do I check if a device is mounted?
How do I eject a cd?

"How do I check if a device is mounted?"

Use the mount command without any parameters to give you a list of all mounted devices and search the output using grep:
mount | grep (grep parameters)
if test $? -eq 0;

"How do I eject a cd?"
Use the eject command.

Be prepared. Create a LifeBoat CD.
