Basically, this script makes locked-down, read-only PPTX files editable.
Created out of necessity for the Technion's 234218 Data Structures course.
The idea was shamelessly stolen directly from this repo.
Simply run the script as following:
./pptx-breaker.sh READ_ONLY_PRESENTATION.pptx
You can even run this script on multiple files, for example:
#!/bin/bash
for presentation in *; do
./pptx-breaker.sh "$presentation"
done
Good luck on your tests and happy printing!
