I want to save a trajectory_msgs. How can I do that?
If you want to save a particular text message directly to a file you can do
rostopic echo -p /your_topic/goes/here > /path/to/your/file
you won't see any ouptut here, but in your file you'll see the message in a CSV format.
Just record the topic using rosbag.
Then replay the message(s) or analyze them off-line using rxbag or the rosbag API.
