How to wait in bash for a result?

I would like to write a script that first calls supervisorctl reload then it runs and runs again supervisorctl status until it returns a zero exit code.

What is the proper way of doing that?

>Solution :

# first calls supervisorctl reload
supervisorctl reload
# runs again supervisorctl status until it does not return a non-zero exit code.
while ! supervisorctl status; do
   :
done
