Make a ISO image from a single entire cd
 

In others machine I can see GUI option to build a ISO image from a cd. In this FC4 can see the option, how to do command mode?

try:


mkisofs -r -o your_file.iso /mnt/cdrom

change your_file.iso to the filename you want to give it and /mnt/cdrom to the location of your cd drive.

I don't recall either exact command, but I know you can directly ready the CD to a .iso file, that when burned onto a new CD would be a closer duplicate of the original.

Alternately, you can read all the files and directory structure from a CD and form them into a new .iso that may be a functional duplicate of the original but may be a less exact duplicate in many ways. That is also a slower process and more demanding of resources on the computer where you do it.

I expect ncsuapex gave you correct instructions for the second of those two choices. Most likely you would have preferred the first.
