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?

    It’s convenience over security, something that creeps in anywhere there is popularity. For those who just want x or y to work without needing to spend their day in the terminal - they’re great.

    You’d expect these kinds of script to be well tested against their targets and for the user to have/identify the correct target. Their sources should at least point out the security issue and advise to grab and inspect before straight up piping it though. Some I have seen do this.

    Running them like this means you put 100% trust in the author, the source and your DNS. Not a big ask for some. Unthinkable for others.
