If you need to burn a CD or DVD from an
ISO file
from the command line on a Linux system, you can use the
cdrecord
command. If you include the -v argument to the program, you will
see verbose information on the actions performed by the utility and the
progress as it writes to the optical disc. E.g.:
$ cdrecord -v kali-linux-2017.1-i386.iso wodim: No write mode specified. wodim: Assuming -tao mode. wodim: Future versions of wodim may have different drive dependent defaults.

When the program is finished you can use the eject command to eject the disc.
$ eject $
If you issue, the command cdrecord it runs the
wodim program. On a CentOS Linux system, you can see that
cdrecord is a link to the wodim utility at /usr/bin/wodim.
