Davew_, r.sh was a copy just to test some stuff.
Small tutorial:
As user root, create /root/runall.sh and do chmod +x /root/runall.sh and then edit it with vim or any other editor.
Example:
cd /home/paintball/paintball2/
sudo -u paintball2 screen -A -m -d -S myserver1 ./myserver1.sh
Then as root, do crontab -e, pick any editor you want to use and append @reboot /root/runall.sh to the end of the file and then save it
