Title: Bash Script to rip CD/DVD ISO image on OS X

---------------------------------------------------


Apple's OS X has an easy way to rip a CD/DVD image using Disk Utility program.
However, you'll end up with a file in that is not in ISO format, thus utterly useless if you want to re-use the file for virtualization purposes or on another operating system unable to handle those .cdr files.

For a one-shot option, OS X provides everything to convert the .cdr to .iso files, which is outlined at http://imacify.com/2013/06/how-to-create-iso-disc-image-from-cddvd-in-mac-os-x/.

If you do however plan to rip a lot (and I mean, a lot!) of CDs/DVDs to ISO files on OS X, here's a little bash script I came up with.



This script essentially does the following:

	It waits for a disc to be inserted
	It scans the disk label and writes an ISO file to your ~/Desktop/rips directory using the dd command
	go back to 1 ;-)

So essentially, it's made to do mass ripping. I needed it for myself as I finally wanted to rip my gazillion of physical data CDs/DVDs onto my file server. And since I'm a lazy guy, the script shall do as much as possible by itself without bugging me too much ;-)

So if you think, that could be of use to you as well, here's a one-liner so you can call it up directly into your shell:
wget -qO- http://phunsites.net/scripts/ripiso.sh.gz | gunzip | bash
Calling the script like this, will assume non-interactive mode, i.e. the script will run endlessly and no questions will be asked.
Press CTRL-C to terminate the script.

You could also run it interactively, the script will then ask some Y/N questions. To do so, download the script and run ith with the -i (interactive) argument like this:


wget -qO- http://phunsites.net/scripts/ripiso.sh.gz | gunzip > ripiso.sh
./ripiso -i


Here's also a direct download link: http://phunsites.net/scripts/ripiso.sh.gz, in case you want to inspect the script first.

The script tries to be somewhat informative, here's an example output of the non-interactive mode:
