On node 16.9 console.log doesn't produce a non-zero exit code, but process.stdout.write does, and gives me a decent error message as well:

  internal/fs/utils.js:332
      throw err;
      ^
  Error: ENOSPC: no space left on device, write
      at writeSync (fs.js:736:3)

This is because console.log isn't the equivalent to the post's printf. It is purposefully opaque to the application (and applications should not assume anything happens with the input).[0]

> Its main output is the implementation-defined side effect of printing the result to the console.
