Have you done "chmod +x ghettoVCB.sh"?
You need to check everything from top to bottom because there is no such thing as the "zerothick" you have in your log - it is "zeroedthick"
cd into the destination datastore directory and run the script with the full path name. e.g. /vmfs/volumes/ghettoVCB-master/ghettoVCB.sh or whatever is correct and double check your config file
