    Resolved:

    • in this case, command cannot to assign value to variable (value in my example) and simultaneously save value in file. Than must erase string value=$

    • for save result in file just adds >filename

    40 07 * * * curl -d '{"query":"java-middle", "turnOff":true}' -H "Content-Type: application/json" -X POST http://localhost:8080/explorer >/path/filename
