README.md : "to get this to work, curl or wget the following script and run it as sudo"
Linux users: Aye
Installing software to the system should be handled by a package manager, but if you must install something like this, just throw it in a tmpfile and inspect the script before running it.
I know the response to this will be "but the things the script downloads and installs could be malicious", and while this is true, so long as the sources in the install script are fine, I consider this to be a separate issue (but still a big issue).
The issue of trusting source code or binaries is a thing but it doesn't justify copy pasta'ing random scripts in the shell.
Another thing to take note of, there in the past have been bugs in terminal emulators that allowed pasting certain characters that made the text look completely different than what it actually was, so pasting "ls $HOME" could have actually been "rm -rf ~/" for example.
This is what makes it so doable since you don't need any privilege escalation.
The reason why this is a big deal for a lot of people is your ssh keys will give you access to your git repos and other servers unless you have them password protected or use gpg/sk ssh keys which I think a lot of people don't do.
And of course if you can see the known hosts file/bash_history you'll likely have access to more servers to propagate to.
Also things like your browser cache is stored there.
This is why I store keys on a hardware key that requires me to touch it when used and manually start ssh-agent when doing a lot of `git push`.
