I give them the concept and the details I need, and they give me the code. Then I ask for explanations of each process. I make some changes to customize the script to my liking and share the changes with them to check for any errors.

This script is to find out how much memory a certain program uses.
Although the script is in Spanish, there’s an English README on GitHub.
