This asks the program nicely if it can exit, and most of the time a program will comply. Sending “CTRL C” to a program is similar to using the kill command, though with a lower priority (I used level 9 above, and CTRL C is level 2). This is the same process as using the kill command alone, except with a different way of finding the Process ID. Type this command: sudo kill -9 process_ID.Find the Process ID (this is the first number of the output).Type in this command: sudo ps aux | grep -i name_of_program. If you know the name of the program that’s running, you can use the terminal to stop the program from running. Often the name of the process is the same as the name of the program, but commonly on Raspberry Pi this is not the case if you’re running a program inside Python for example, the process name will by python rather than the name of the script/program you’re running. Kill the program based on its nameĪ program running on Raspberry Pi can be stopped if you know the name of the name of the underlying process for the program. More details on the different signal levels can be found here. This command is telling the Raspberry Pi OS to send a “level 9” signal to a process this signal will force the program to terminate immediately. If you are asked for a password, type in the password for your Raspberry Pi “super user” account (by default this is raspberry). Using the kill command terminates the program Type the following command in the terminal to give you a list of all the process running on your Raspberry Pi: ps aux We need to use this new terminal window to find the Process ID. (This happened to me before – I froze my terminal by running a program that never terminated, and then had to figure out how to open another terminal to fix it thankfully Raspberry Pi’s graphical interface makes it easy to open a second one) Step 2: Find the Process ID Open up a new terminal window on your Raspberry Pi.Įven if your terminal is stuck running a program, you will be able to open a second window that we are going to use to fix the first one. To stop a program running on a Raspberry Pi, follow the steps below: Step 1: Open a new terminal window Once you find out this PID it can be used to terminate the process using the kill command in the Raspberry Pi terminal. Kill the program using its process IDĮvery program running on a Raspberry Pi has an ID number associated with it, a Process ID (PID). This guide gives more detail on each of these methods below. If you’re not sure what the program is, use a task manager.a Python script running inside Python), try using CTRL + C If the program is running inside another program (e.g.If you can’t see the program you need to terminate, use the process ID method.Options for terminating a program on Raspberry Pi
