→INVESTIGATION 2: MANAGING PROCESSES
# Issue the following Linux command: <span style="color:blue;font-family:courier;font-weight:bold">(sleep 400; sleep 500; sleep 600) &</span><br><br>
# Issue the '''jobs''' command. What do you notice?<br>You should notice all commands are run in a group as just one process.<br><br>
# Issue the following Linux command to terminate the first job:<br><span style="color:blue;font-family:courier;font-weight:bold">kill %1</span><br><br>NOTE: If issuing the kill command does not work, then you would need to send a STRONGER signal<br>to "'''kill'''" (not "''SIGTERM'' - which is signal ''#15''") the process. The '''SIGKILL''' signal (signal '''#9''') would be required<br>to do this by issuing the '''kill''' command with the option: '''-9'''. <br><br>By the way, the '''ctrl-c''' key combination sends the ''SIGINT''<br>(signal interupt - which is signal ''#2'') to terminate processes running in the ''foreground''.<br><br>
# Issue the '''jobs''' command and make certain there are no processes that are running in the background.<br><br>Let's terminate our Matrix Bash shell process by using the '''kill''' command using that process' '''PID'''.<br><br>
# Issue the following Linux command: <span style="color:blue;font-family:courier;font-weight:bold">ps</span><br><br>
