curl https://some-url/ | sh

I see this all over the place nowadays, even in communities that, I would think, should be security conscious. How is that safe? What's stopping the downloaded script from wiping my home directory? If you use this, how can you feel comfortable?

I understand that we have the same problems with the installed application, even if it was downloaded and installed manually. But I feel the bar for making a mistake in a shell script is much lower than in whatever language the main application is written. Don't we have something better than "sh" for this? Something with less power to do harm?

Am I the only one who cringes when I have to update my system?

How do I know the maintainers of the repo haven't gone rogue and are now distributing malware?

DAE get anxious when running code on computer?

I think for the sake of security we should just use rocks, stones, and such to destroy all computers, as this would prevent malicious software from being executed.

Absolutely. Wanted to try out the famous Python management tool UV last week, installation instruction is like this:

curl -LsSf https://astral.sh/uv/install.sh | sh

Yeah, no thank you.

Is available via pip? You could use venv

Yeah I hate this stuff too, I usually pipe it into a file figure out what it's doing and manually install the program from there.

FWIW I've never found anything malicious from these scripts but my internal dialogue starts screaming when I see these in the wild, I don't want to run some script and not know what it's touching malicious or not it's a PITA.

As a linux user, I like to know what's happening under the hood as best I can and these scripts go against that

So basically the install instructions for Lemmy? No Lemmy data is safe.
