Common Linux and ROS commands, linux operating system

I feel that some tools are always forgotten even if they are simple. The right tool is notepad and graffiti.

Linux:

ROS:

1) view image topic by ROS

Rosrun image_view image: =/imagetopic this: = actually changes the name of its built-in topic.

2) view topic content by ROS

For example, I have a topic named/ardrone/IMU,

Rostopic echo/ardrone/IMU

3) rqt

Sometimes you need to display the content in the topic in a curve. rqt is a good method. Enter rqt directly in the command line and configure it manually later.
