Running linux downloads - total noob

rated 0 times [ 1] [ 0] / answers: 1 / hits: 1859 / 2 Years ago, sat, july 9, 2022, 10:37:04

I am a COMPLETELY new user to linux and have been using most of my programs through wine. Take for example this program : http://www.atlauncher.com/download/jar/ which, when unpacked has no executable files. I'm not sure if I am looking for the wrong type of file but I would really appreciate some help on how to get downloads like this with no obvious runnable files up and running.

Thanks in advance

You don't extract .jar files, because they are Java Archives and should therefore be executed using Java (or in case of a library included in your project). Ubuntu opens .jar using the Archive Manager by default because it is actually a ZIP file.

So you should install Java first. If you haven't already, you can execute the following commands to install OpenJDK (an open source version of Java):

sudo apt-get update

sudo apt-get install openjdk-7-jre

Now you can open the .jar file using java -jar file.jar in the terminal or by double clicking it in your file manager.
