rostopic is not the right command for republishing the content of one topic as a separate message on another topic since it does not evaluate the arguments passed ('[chatter, 0.0, 0.0]' '[0.0, 0.0, 1.8]').
rostopic pub -1 /turtle1/cmd_vel geometry_msgs/Twist -- '[chatter, 0.0, 0.0]' '[0.0, 0.0, 1.8]'
The relay_field node from topic_tools (http://wiki.ros.org/topic_tools) is more appropriate for your purpose as it provides this functionality. The command for this would be
rosrun topic_tools relay_field /chatter /turtle1/cmd_vel geometry_msgs/Twist "linear:
x: m.data
y: 0.0
z: 0.0
angular:
x: 0.0
y: 0.0
z: 1.8"
