So I've been running the server fine for a few weeks now, but as I added more mods I could tell it was slowing down. I looked up how to add more ram and saw that you could use a .command file like on the vanilla server. I have been running the server by double clicking the jar file. Made the command file, gave it privileges with chmod a+x, but when I ran it I got Error: Unable to access jarfile. I checked to make sure I have the name right in the command file. Help please!
