Hasta La Motion!

The following script I am using for getting the information of start_frame, end_frame, width & Height of the given scene. This is working in the nuke GUI.

My problem is that I need to run this script through the terminal without opening GUI of nuke
I gave the following command

COMMAND:
/usr/local/Nuke6.0v6/Nuke6.0 -t test.py /home/narasimham.k/Desktop/test/test.py /home/narasimham.k/Desktop/test/test.nk

print str(int(nuke.root()[‘first_frame’].getValue()))
print str(int(nuke.root()[‘last_frame’].getValue()))
print nuke.root()[‘format’].value().width()
print nuke.root()[‘format’].value().height()

Please help me
