Those scripts can be used to tidy up a Powerpoint file by renumbering the name of the layouts. If your master is named "Covers" then the layouts will be named:
- Covers 1
- Covers 2
- etc...
The script will NOT update your original file but will create a new file appending "NEW" to the filename in the same folder of the original file. Nevertheless you should always make a backup of your files before running these scripts to prevent any loss of data.
Running is straightforward:
./rename_layouts.sh <path to pptx file>
The script will rename all layouts for master slides that start with some words. You can check and change the list of words by changing the matches variable in the update_layouts.sh script.
These scripts were tested on MacOS.
