Supernode - nisStart.sh

Can Someone give me an example nisStart.sh for supernode configuration on Debian?

Do I need to include:
#!/bin/bash
Java –Xms768M –Xmx768M –cp “.:package/nis:package/nis/:package/libs/” org.nem.Deploy.CommonStarter

As well as its original text:

cd nis
java -Xms1536M -Xmx1G -cp “.:./:…/libs/” org.nem.deploy.CommonStarter
cd -

or just the top part?
Thank you

This seems to work: I have a 2GB server, so I upped the memory to 1536M.

#!/bin/bash
java -Xms1536M -Xmx1536M -cp “.:package/nis:package/nis/:package/libs/” org.nem.Deploy.CommonStarter

In /home/myusername only the following 3 items exist:
package (folder)
nisStart.sh
config-user.properties
