What changes are you trying to make? (e.g. Adding or removing code, refactoring existing code, adding reports)

I have updated the shell script using the comments provided.

What did you learn from the changes you have made?

I have learned how to create directories/folders, copy and create files, edit scripts in bash terminal, etc.

Was there another approach you were thinking about making? If so, what approach(es) were you thinking of?

For the final comment (8): I was thinking of first creating the text file and then listing the files in the subfolders in that text file using the following code:
touch data/inventory.txt
ls data/processed/* > inventory.txt

Were there any challenges? If so, what issue(s) did you face? How did you overcome it?

I initially found it difficult to make my script run in any directory. I found help online.

How were these changes tested?

I tested the script in different file path on my computer to ensure it ran smoothly.

Checklist

• I can confirm that my changes are working as intended
• I have tested the script with different file types, and it works as expected
