Create ISO of just the contents of a hard drive

[wweeks]

I've been using the command

dd if=/dev/sda of=/dev/sdb

to copy my hard drives contents completely to another hard drive.
However I need a way to copy just the files on one partition. I don't want the entire partition copied, just the files. I need the code to output them in to an ISO, any on know how to do this? I'd appreciate any help.

Does it need to bee cli? You could simply use brasero to create a cd project and write it to disc (meaning create an ISO).

If you need it to be cli then take a look at the man pages for growisofs or genisoimage. I believe both of them can do what you want.

Doesn't need to be cli, just needs to be bootable when I'm done.
