GUI Hung? Revert to CLI

The more GUI fails me, the more I find myself back in the CLI.

This is 4 different #PowerShell (version 7.5.4) sessions, all running in W11 25H2 Terminal. WHY you ask? Great question, because my Microsoft Excel is currently a gray screen with a blue spinning curser of DEATH! I have almost 1,000,000 rows of data to parse/process/dedup/filter/exclude/prune. This should be fairly simple operation for Excel, but NO!

This is where I find a little AI (ChatGPT GPT-5) and #PowerShell come in quite handy. If asked, Python might handle this much faster but I’m not familiar with it and would rely too heavily on AI assistance. At least with #PowerShell I can figure out some errors and understand most of the code.

The end game is matching folder permissions from one platform to another at a certain folder hierarchy level. Maybe matching is the wrong word, how about clarifying. I’m taking > 1 million folders and removing a certain level of subfolder and then applying a permission group to a certain folder via a template. The template will run in python on the destination. The issue is the source data is not consistent enough to apply a constant template so I have to manipulate the source data to make it consistent enough. I can’t share more details without revealing too much proprietary information but if you’ve ever moved a massive amount of data (100+ TB) from one platform that spans 20+ years and has NTFS style permissions to another platform that is not NTFS then you might know what I’m referring to.

It is fun to see all the #PowerShell windows fly by with the colors and output. I have one screen manipulating the data which are a ton of smaller TXT/CSV files, and another window monitoring the output folder. I also have some checks and balances in place and countdowns and timers and heartbeat so if the process stops I can pick back up where I left off. I also log EVERYTHING. I am also setting up this process to run on different folders for the future.
This is a chain of thought and not well typed. I tried to write the bulk of this on my site but the mobile app is failing me right now.

UPDATE: I had to revert my website from backup 24 hours ago and now I can post. Below is the error I received.

UPDATE: As of the next morning, it had gone from 25 batch files to 125 batch files and still counting…
