Forge Server Launch Script is not working

[ProfessorTechno]

I have a forge server for 1.7.10 and I have Java 8 v191 and used this launch script

#!/bin/bash
cd "$(dirname "$0")"
java -Xms4G -Xmx4G -jar forge-1.7.10-10.13.4.1558-1.7.10-universal.jar nogui

and it still won't work, but if I just double click on the forge.jar it works.
