Running the command creates a file in project root

After running the command there's a file in my project's root named 'Line Count', which is fine, but when I close the tab opened by line-count, this file stays there. I would expect this to be a temporary file. I suspect this has something to do with the autosave package saving the tab upon opening it, because disabling autosave fixes this.

I'm on Linux Debian, Atom 0.187.0
