Mark as executable

Question

I'm using Elementary OS. How do I mark a .jar file as executable. I do have JDK installed, but I get an error saying it isn't marked as executable.

Answer 1

You can either open a terminal and run

chmod +x yourfile.jar

or right-click the file in the file manager, open the Properties window, switch to the Permissions tab and check the Execute box in the Owner: row.¹

^{1: At least that's the way it works in Nautilus/Files (GNOME's default file manager) which Pantheon's Files seems to be resembling quite closely.}

You could also avoid the need to mark it as executable by using the Java executable to invoke it:

java -jar yourfile.jar

• Daniel Bejan: I tried using nautilus to go to properties and check the box with execute but the second after I check it, it unchecks by itself,which is really wired....
• n.st: Have you tried setting it using chmod and checking if it persists?
• Daniel Bejan: I managed to run it with chmod eventually...Thank you!
