Burn CD or DVD from ISO file (CLI)

Assuming that you already have an ISO file and all you want to create CD based on the ISO 9660 standard. You can burn an ISO using below command,

# cdrecord -v -pad speed=1 dev=0,0,0 daddy-linux.iso

If you are not comfortable with the above mentioned process, follow below method.

First Identify CD ROM letter from /dev/

# ll /dev/ | grep -i cdrom

lrwxrwxrwx  1 root root	3 2010-09-30 15:13 cdrom -> sr0
lrwxrwxrwx  1 root root	3 2010-09-30 15:17 cdrom1 -> sr1

Here, sr0 is our first CD drive and you want to use same drive for burning,

# dd if=/root/Download/daddy-linux.iso of=/dev/sr0 bs=512

Here, if = Source place of an ISO file and of = Destination place or where to write.
