From some of the other question I realized it is possible to remap the namespace of node on the command line using rosrun. But it is not working for me..

The syntax i tried is ,

rosrun somepkg somenode:="new_namespace/somenode.py"

and many other variations of it.

Could someone please tell me what is the correct way to remap a node to another name space on the command line while using rosrun?

You can only use remapping arguments (the := syntax) for parameters and topics. If you want to push a node into a namespace on the command-line, you would do it like so:

$ ROS_NAMESPACE=new_namespace rosrun somepkg somenode

This will force somenode to be in the new_namespace namespace.

Look at: http://www.ros.org/wiki/Remapping%20Arguments

I'm not sure if you maybe want to only change the __name but not the namespace.
