Is the killtree command on line 55 a bash script of some kind? I'm trying to use your script to start a server. Thanks.

Line 73, on my install in ubuntu I had to edit to $MTPATH to $MTPATH/worlds so that the backup would properly call.
Also the stop server uses a killltree command, which looks like a custom additional script
