New cost command is available on hexagon. The new command conforms with the NOTUR standard and has the same basic functionality as on the other NOTUR resources.

cost - will show your used CPU hours for the current allocation period.
cost -p - will show total used CPU hours of your connected projects.
cost -P - will show report for another allocation period.
