A (python3) script for burning cd/dvd copies on multiple drives in linux

These scripts help automate the process of burning copies of different discs on multiple drives for a project I received. It doesn't seem like there are any linux tools in recent distro versions to do this (as civilization is past burnable media nowadays) and manually doing it was out of the question.

Not much effort (euphemism for no effort) has been given to make these scripts robust for any other use case.

Requirements

• Linux (tested on Ubuntu 16.04)
• Python 3
• At least one optical drive showing up as /dev/srX
• wodim for the actual disc burning (or any alternative that can be run from the CLI)
• checkmedia to let us know if media is loaded
• sg_map tool from sg3-utils package (and super user authority to run it) to map /dev/srX to /dev/sgX. It seems wodim somehow works much faster when accessing sgX devices. Can be skipped if not the case.
• (optional but very handy) tmux to run different burning instances in the same window.

How to burn

Call burn.py adding the number of required copies needed and the complete path to the ISO that is to be burned. It will scan the system and create X shell files called burn-instance-X, where X is the number of available cd/dvd writer drives (assuming readonly drives are extinct since at least a decade this will do fine). Example of use: python3 burn.py 100 /home/user/ubuntu.iso

Now you can call each burn-instance-X individually in a terminal session, or use tmux-start.sh to open up 16 panes in a new tmux session/window and call the respective script in each pane.
