In which way is it untrusted? If you use CachyOS, you use their binaries, that could contain anything at all inside of them. Do you draw the line at a shelll script you can read yourself?

I don't use CachyOS nor do I know anything about their team and I haven't used the script either. My point was just that I would trust OS maintainers more than some random guy on the internet.

I have checked again and it seems the script I was referring to was actually from a mod on their community forum. Not sure if this is a maintainer as well or not.

My point still stands, if you trust the source and checked the code that nothing shady is going on, it is perfectly fine to run a script. Even if it is just an additional check after you cleaned it manually. Maybe you have missed something.

You can just check it and it wouldn’t be untrusted anymore…

You could inspect the script, it should be a one line shell command
