sudo`supervisorctl` reads configuration from `/etc/supervisor/conf.d` and runs whatever files if finds there.

a typical `conf` ile looks like:

   [program:cascada2]
   command=/usr/bin/python /home/pi/mypi/cascada/server/cascada2.py
   directory=/home/pi/mypi/cascada/server
   autostart=true
   autorestart=true
   startretries=3
   stderr_logfile=/var/log/cascada/cascada2.err.log
   stdout_logfile=/var/log/cascada/cascada2.out.log
   user=root
   environment=SECRET_PASSPHRASE='this is secret',SECRET_TWO='another secret'

you may have to `>supervisor reload` then `ctrl c` the `sudo supervisorctl` to get a new program running forever
