使用的是contes的系统

我知道有这东西 。但是该怎么设置 。我弄得一直不重启 。就连蹦服也不会重启 。就有保存可以用 。

while : ; do
  echo "run server now ,  you can't close"
  java -Xmx2000m -Xms2000m -jar ./craftbukkit.jar
  echo "Restart after 5 seconds , you can close now"
  sleep 1
  echo "Restart after 4 seconds , you can close now"
  sleep 1
  echo "Restart after 3 seconds , you can close now"
  sleep 1
  echo "Restart after 2 seconds , you can close now"
  sleep 1
  echo "Restart after 1 seconds , you can close now"
  sleep 1
done
