Ctrl+C can't kill the ros2 run

edit

Hi Guys,

I have one ROS2 subscriber and one ROS2 publisher. To ease the execution I have written a bash script which calls both nodes and executes them simultaneously.

Content of the bash script is as below:

ros2 run perception_publisher publisher &  
ros2 run behavior_planning_hmi hmi

Execution works fine, however when I try to kill the execution by pressing Ctrl+C script is not being terminated. It ends up running continuously that I have to kill using the process ID.

Is there a way I can kill the process gracefully?

Thank you,
KK
