I have been trying to install forge on my Ubuntu 18.04 server, but any tutorial I find is only for windows servers. Any ideas?
EDIT: I worked it out! I am going to list the steps in case anyone else needs it:
1. run "java -jar [forge installer jar here] --installServer" in a separate directory just for your server files
2. run "mkdir mods" in the same directory as your forge installation
3. put any mods in the new mods folder
4. when ready to run your server run "java -Xms512M -Xmx3G -jar forge-[forge version here]-universal.jar nogui"
Note change -Xms to the minimum RAM to allocate and -Xmx to the maximum RAM to allocate
