Automatically give file extensions to files without them. For Linux/BSD. Suggestions/patches are welcome.
I wrote this, because it seems like I had a bunch of downloads without file extensions. That's all it does. It automaticaly renames files that do not have extensions, and skips files with recognized extensions.
Installation is just downloading the single script, and running it like any other script with no dependencies. It does require xdg-open and python3 -m mimetypes, which should be present on modern distros.
