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

i'm not getting the warning "WARNING The following node subscriptions are
 * /rosout:
   * /rosout"
as said in the tutorial 
Getting started with roswtf 

and no answer to previous query
"in the tutorial 
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 "
