I was trying to record a bag file using rosbag record /my_topic. However, apparently, there is not autocompletion for the topics, if I click on the tab key, after having written rosbag record. Is this the normal behaviour? Actually, I can see the ROS topics (including the ones I am interested in recording) by issuing the command rostopic list. Autocompletion seems to be working for other commands.

I tried it on my machine. On ROS Melodic, the current autocompletion behaviour of rosbag record and other subcommands of rosbag is to insert a file name, so when you press the tab key, the computer inserts the name of the only file in the current directory or shows you a list of the files in the directory if you have more than one file. Nothing will be inserted if you don't have any file in the current directory.

Ok, but I would like the autocompletion to work for existing ROS topics, not folder names.

I am not sure of how tab completion is configured, but I think this would have to be done by the developers of ROS. You may be able to configure it manually too, so I recommend you check online for how to do that.

I just learnt that tab completion for ROS utilities is enabled by the rosbash package. You can check this page for more information.
