With this knowledge we can then stop (pause/suspend) a job using the command kill -stop PROCESSID. Using the command jobs -lВ produces a list of running jobs, their job number in and their process ID:ДЇor example, test.py is running as process ID 10262. Jobs has the ability to list running or suspended jobs, to stop a job or to continue a job.ДЇor this example I have copied my Python script four times, modifying the output depending on the script number and then set them all running in the background. However, there is a solution for that and that solution is jobs. With the possibility to start multiple jobs and have them all running in the background it could be very easy to lose track of what is running. To bring the job back to foreground we need to enter fg %JOBNUMBER, so in our case fg %3

With our script stopped (paused) we need to note the job number, in this case and then enter bg %JOBNUMBER:ДЄnd our job then resumes running in the background. First we need to start the Python script running:ДЄnd once the script is running we need to pause it using CTRL Z ctrl z mulitask The BG % / FG % (Background / Foreground) method is slightly different as it allows us to move a running command to the background after it has started running. The & method continues to output the Python script but allows for new commands to be entered. The in the above is the commands job number and the 10088 is the commands process identification, more on this later. This command is telling the terminal to open Python3 and run test.py in the backround, which frees the terminal up for other commands, for example pinging. The ampersand (&) method is achieved by placing a & at the end of the command.
