Hey guys not sure why but when i execute the script i get the correct result but then it says command not found not sure why can anyone see anything wrong with my code below?

I just want to print how much quota i have used in my home directory

#!bin/sh


`quota -v | grep ^/home | awk '{print int($2/$3*100)}'`

echo "your quota is being used"
2 
#!bin/sh


q=`quota -v | grep ^/home | awk '{print int($2/$3*100)}'`

echo "your quota is being used = $q "
3

or

echo "your quota is being used = `quota -v|awk '/^\/home/{print int($2/$3*100)}'`"
