In two places the second "password" after : must be replaced with the real password, for example "password": "my_secret_password". If using custom port, replace 33777 with correct port in both places.

If you save the script on top of the post as /root/optimize.sh and add above line in /root/crontab, and run crontab /root/crontab the script will be run every 5 minutes. All output from script will be discarded. 5 minute interval should be enough to optimize all the subwallets even if they are used for mining.
