Re: [ros-users] rosbag record from launch file

This is because roslaunch does not use your local path. If you
assumed you were using your local path, it wouldn't necessarily make
sense if you were to launch a node on a remote machine.

As present I believe your bagfiles are most likely ending up in ~/.ros

As Dan suggests, you should generally specify an absolute path for
your bag. In rosbag the option is now -o or -O (not -F).
