From Virtualizor Wiki
Virtualizor has Command Line tools which can be used to speed up operations. This guide shows you how to use these command line options.
To delete a VPS run the following command as root :
/usr/local/emps/bin/php /usr/local/virtualizor/cli/deletevps.php VPSID [OPTIONAL]noprompt
- VPSID is the VPSID (not vps name) assigned by Virtualizor.
- noprompt will not ask for any prompt and delete the VPS. It is optional.
