Let$$s get your output file prepped and ready to go for the lab.

$1)$ whoami $>$ week$13.$out

$2)$ echo $>>$ week$13.$out

$3)$ date $>>$ week$13.$out

$4)$ echo $>>$ week$13.$out

$5)$ echo $***********>>$ week$13.$out

$6)$ echo $>>$ week$13.$out

Now that we have your output file setup with your name, date, and time, let$$s get started.

Let$$s look at a couple commands. First, we can see your current running processes.

$7)$ ps

Notice the bash shell $($parent process$)$ and the ps command have a Process ID $($PID$)$ number assigned to them.

We can create a process that runs in the background so that we can see an additional process.

$8)$ sleep $900$ &

This will create a background process with the sleep command and assign it a PID. Let$$s see that now.

$9)$ ps

Let$$s update the week$13.$out file.

$10)$ ps $>>$ week$13.$out

$11)$ echo $>>$ week$13.$out

$12)$ echo $***********>>$ week$13.$out

$13)$ echo $>>$ week$13.$out

We can see only the background job $($process$)$ with

$($NOTE: If there were more than a single background job, we would see all of them using the following

command$)$

$14)$ jobs $-$l

Update week$13.$out file.

$15)$ jobs $-$l $>>$ week$13.$out

$16)$ echo $***********>>$ week$13.$out

$17)$ echo $>>$ week$13.$out

Notice that the PID number is the second field. You will need that PID for the next command. Now, let$$s stop

or kill that process.

$18)$ kill enterPIDhere

$19)$ ps

Notice that the sleep process has been terminated. Let$$s update the week$13.$out file.

$20)$ ps $>>$ week$13.$out
