Please provide screenshots for each part. Some syntax may need to be corrected if necessary. Comment is needed for each part.

Log in to your VM machine and provide a screenshot of your work and make sure to use MS word to comment in each screenshot. It's not enough to past the execution of the command to get a full credit. 

In this homework lab, you will manage processes. You will view running processes several ways and examine their priorities. You will run a sample program, observe it, and then set it to run in the background. While it is running, you will monitor it, then send a kill signal to its job ID. You will schedule processes to run once at a specified time, then subsequently set it up to run at specified intervals.

Log in to the VM machine and start working.

Part 1: View the current processes using the ps command. The -aux option will show ALL of the processes running on the system. View all processes using the ps -aux | more command piped into the more command. View all of the processes using the pstree command. View the current processes using the top command. The top command shows current processes in real time and stays active until ended with the CTRL+C keystroke. Use CTRL+C to end the command. Clear the screen.

Part2: Run the yes command in the foreground by typing yes and then stop it using the CTRL + C keystroke. Run it and send output to /dev/null using yes > /dev/null. The shell prompt will not return until the process is stopped, again using CTRL+C. RUN the process in the background by adding the ampersand metachracter (&) to the last command. A space before the ampersand is optional. Now you get the job and PID output [1] 2218 and prompt returns.

Part 3: Check the job by typing the jobs command. Another way to check it is use the ps command; type that next. Send a kill signal to the yes process using its job number. Type kill %1. Use the jobs command to verify the termination of the process. View the list of available kill signals by typing kill -l. Clear the screen when you are finished.

Part 4: Use the ps -l command to view the nice values of the currently running processes. Record the nice value and the priority of the ps command. Clear the screen.

Part 5: Make a simple batch file named atbatch and schedule it to run the atfile using the at command. To create the file use the cat command as follows: cat > atbatch. On the next line, echo "This file was created by the at command" > atfile. Use CTRL+C to close the atbatch file. Use the date command to get time. Use the t command to run the command in one minute from the time shown. The command will be at 5:25 AM -f atbatch. The job will be confirmed. After a minute, type cat atfile and you should see that atfile was created with the line, "This file was created by the at command".
