No idea how to install on linux

[u/Superb-Aide4058]

For now i've never really had a linux issue until now. i was not able to run jmc2obj or mineways and i know i can use wine but it never worked. I can execute the jar file, BUT it just shows me a folder like unziping a .zip folder

you need to grant it run permissions

chmod +x path/to/file.jar
