rostopic problem

in flag

When I enter rostopic in my terminal and press tab button to get the instructions, something occurs like below:

racer@racer-Dell-G15-5511:~$ rostopic 
.99-realsense-libusb.rules  .local/
.bash_history               .mozilla/

.ICEauthority               .xsession-errors
.ignition/                  .xsession-errors.old
librealsense/

I don't know how to fix this because I am just a rookie.

I have added source ~/catkin_ws/devel/setup.bash into the ~/.bashrc

You actually typed "`rostopic `", that is, with a trailing space. Your `TAB` autocompleted from the filenames in the current directory. Try `rostopic -h`.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
