How to uninstall this commad ?

Yes, I ran the A.B.T. script by denis-g but did not install Cryo Utilities

Explain to me why I should do a ‘revert’ by A.B.T in the Medium post if I want to install SDWeak ?

What is "ananicy-cpp" ?

If I’m understanding this right, you have run the script linked and also installed CryoUtilities separately?

In that case, I’d run A.B.T’s “revert” script in the Medium post (looks reasonable at a glance?), and uninstall CryoUtilities using the instructions on their GitHub.

I think you would definitely want to have CryoUtilities uninstalled before SDWEAK, since ananicy-cpp would probably conflict. But I would **highly** recommend backups before running arbitrary commands on your deck 😅

Now, I'm hesitating to remove all the scripts from A.B.T because it's not the same as Cryo Utilities and SDWeak. I found out how to remove the scripts in a blog by A.B.T. Why did I want to remove the scripts from A.B.T.? Because I saw the instructions from SDWeak saying "Before installation, be sure to remove Cryo Utilities if it was previously installed.". Will it be the same case as the A.B.T. scripts? Will there be any issues if I install SDWeak?

Changes made to `/etc` are kept in an overlay partition.

IIRC SteamOS reinstalls itself every update. Just updating the software will probably undo all of these changes.

If you run that command now, it doesn't do anything because the script it tries to download doesn't exist anymore.

If you ran it when the script still existed, the only way to "uninstall" it is to know what the script did. And we can't know without the file.

The guide lists a bunch of things, are you trying to undo them all? If so, how come? If you're looking to sell the steam deck, doing a factory reset might be the better choice

I didn't understand what you mean. This command allows to install on Steam Deck under SteamOS to improve SD performance, I used this guide in the past. But I don't know how to uninstall it, that's what I want

I don't think it will be possible because I have never made a backup on my Steam Deck

I think you may be misunderstanding what the command did. This command basically downloaded a shell script with `curl`, then ran it with `sh`. If you’re familiar with Windows this is equivalent to downloading and running a Batch or PowerShell script.

EDIT: someone else has posted the shell script you ran. You essentially need to manually undo whatever is in the script in the terminal.

Do the opposite of all this, assuming you ran this script some time between 2024 and now:

https://github.com/denis-g/steam-deck-optimization-guide/blob/072642922f86214ed9a4507ec8b93e0a9a86fb12/scripts/steamos_optimization.sh

There is no file at that URL (anymore).

If that was the case when you tried this, nothing happened.

If there was a script there when you did this, the only option is to restore from backup.

By far the simplest solution would be a factory reset.

Based on what others have posted: that script created (or possibly overwrote without making backups) a number of system files. You would need to figure out what, if anything, was in the original files and manually restore them.

This is a great example of why devs need to stop using sh scripts to setup their software. Perhaps with an immutable filesystem this is simpler, but surely there's a better way.
