A beautiful and convenient startup script for a Linux server

Information

I want to point out right away that the script is not mine! I just improved this script and added useful flags and new settings to it, as well as improved the old ones!

Features

ALL FUNCTIONS CAN BE DISABLED!
• Creates a new screen and runs the script there! (It can also be automatically connected there) (And u can select screen or tmux)
• Set a name for the process in top, htop, etc.
• If not specified the .jar file of the server core it will ve found automatically
• Specify the server port right there!
• You will be able to update chunks when you upgrade to a new version!!!
• Enable auto restart when the server is stoped for any reason (You can also configure how fast it starts after stopping)
• You can specify the folder where the worlds will be stored!
• Change the main name of the worlds. (The same as the level-name in server.properties)
• Run the server on a Java version higher than the one supported by the Core!
• Specify the command to run.
• Access to profiling
• Prevents error <<java module.base does not "opens java.lang" to unnamed module>>
• Configurable debugg mode.
• You can also specify a file with parameters for log4j (Only .xml)
• The flags for your server are already configured (They change automatically depending on the type of server)

The script also works freely with both Bukkit servers and Proxies!

If you have any ideas on how to improve it, then write them in the comments! You can also write if there are errors or problems with the launch.
