To copy a cd within linux is a very easy task to do on the command line :).
The if is the input, in this case it is the /dev/cdrom device, and the output (of) is the file.iso placed in the /home/<user> directory
dd if=/dev/cdrom of=/home/<user>/file.iso
to burn the iso back onto another disk, just
-v means verbose, tell you what is happening, with using the device(dev) and then the file to burn to a disk.
cdrecord -v dev=/dev/cdrw /home/<user>/file.iso
There is gui's to do this as well, but just as easy to use the command line at times. |
