-
   script <file.py>       Send a Python script file to Houdini and execute it.
-                         Example: hhb script ./examples/create_pyro_setup.py
-
   get-selected           Print paths and types of selected nodes.
   get-param <parm>       Get value of a parameter on the first selected node.
   set-param <parm> <val> Set a parameter on the first selected node.
   get-inputs             Print input connections of the first selected node.
   status                 Check if the bridge port is open.
