How IntelliJ IDEA installs shellcheck
Whatever it does, you end up with a statically linked binary in
Intellij IDEA 2019.2 ships with a new first-party plugin, Shell Script. When you’re using it, it’ll put up a banner asking you if you want to install shellcheck to verify your shell scripts. That’s all you get, and then you have to decide between “Install” and “No, thanks.”
“No, thanks” is like taking the blue pill. It’ll never ask you again, and you’ll belive whatever you want to believe about how robust your shell scripts are. So there’s definitely some pressure to click “Install.”
What happens when you click “Install” there? I mean, practically, as the sysadmin of your own computer, you can’t let them do whatever, right?
Will it install shellcheck with your distro’s package manager?
Will it set up Brew, use Brew to install Haskell, and use Cabal to install shellcheck?
curl | sh a script from somewhere?
Will it add a JetBrains employee’s public key to your authorized_keys file so they can SSH in and clone the source repo and compile shellcheck with optimizations specific to your machine’s CPU features?
And before you read this article, you’d wonder:
after they compile it, will they put it in
Or in the root of your home directory, because they don’t have your sudo password?
Apparently it downloads a prebuilt version in a tarball from Bintray over HTTPS, extracts it, and it makes it executable. Well that’s not too bad.
My last post was about either When volume 19 is loud enough or Highlight All in Firefox 65. Find out which.
