when i run just roscore and try the commands 
$ roscd
$ roswtf

i'm not getting the warning "WARNING The following node subscriptions are
unconnected:
 * /rosout:
   * /rosout"
as said in the tutorial 
http://www.ros.org/wiki/ROS/Tutorials/Getting%20started%20with%20roswtf
Getting started with roswtf 

and no answer to previous query
"in the tutorial 
http://www.ros.org/wiki/ROS/Tutorials/UsingRxconsoleRoslaunch
UsingRxconsoleRoslaunch 
the last rxgraph shows that the /rostopic-aqy is publishing /rosout.
but my rxgraph doesn't have that connection. /rostopic-aqy publishes only
turtlesim1/command_velocity "
