Excellent advice on carving it in a stone and being too stubborn to quit. So much of what is seen is sugar coated instasnap filtered that hearing Leverage your Strengths and work hard is reassuring.

This course really goes in depth with shell commands, and navigating the windows and Linux OS'It was very informative, and the tests walk you through using the commands by using virtual machines.

Process Management

In the fifth week of this course, we'll explore process management. As an IT Support Specialist, it is important to use system tools to read and understand process statuses of machines. We will cover ways to start and terminate a process in Windows and Linux. We will also apply troubleshooting tools to solve problems with processes and resources. By the end of this module, you will use Windows and Linux commands to do practical process maintenance.

In earlier lessons, we talked about processes.

We saw some examples of how to manipulate them with signals.

Let's expand on that idea, Process Management,

by looking at some of the things you can do to manipulate processes.

In Windows, we've looked up programs like Task Manager,

the PowerShell command like Get-Desk process,

and the Task close utility, to name a few.

We've also seen how to send a running processor signal through Control C,

but there's another Process Management tool we haven't talked about

which lets you do things like restart or even pause processes.

This tool is called Process Explorer.

Process Explorer is a utility Microsoft created let IT support specialists,

systems administrators, and other users look at running processes.

Although it doesn't come built into the Windows operating system,

you can download it from the Microsoft website which I've

linked to in the supplemental reading right after this video.

Once you've downloaded Process Explorer and started it up,

you'll be presented with a view of the currently active processes in the top window pane.

You'll also see a list of the files

a selective process is using in the bottom window pane.

This can be super handy if you need to figure out which processes use a certain file,

or if you want to get insight into exactly what the process is doing, and how it works.

You can search for a process easily in Process Explorer by either pressing Control F,

or clicking on the little binocular button.

Let's go ahead and do a search for the notepad process we opened up earlier.

You should see C\Windows\System32\notepad.exe

listed as one of the search results.

If you see something that says notepad.exe.mui, don't worry.

MUI stands for multilingual user interface,

and it contains a package of features to support different languages.

Anyways, once you've located the notepad.exe process,

notice how it's nested under the command.exe process in the UI.

This indicates that it's a child process of command.exe.

If you right-click on the notepad.exe process,

you'll be given a list of different options that you can use to manage the process.

Check out the ones that say Kill Process,

Kill Process Tree, Restart, and Suspend.

Kill Process is what you might expect.

Say goodbye to notepad. Kill Process Tree does a little bit more.

It'll kill the process and all of its descendants.

So, any child process started from it will be stopped.

Kill Process Tree takes no prisoners.

Restart is another interesting option.

You might be able to guess what it does just by its name.

It will stop and start the process again.

Let's do that with the notepad.exe process.

We started from command.exe.

Interesting.

After the restart,

notepad.exe doesn't appear as a child of command.exe anymore.

What gives? Well, if you'll search for notepad.exe again,

we can see it's been restarted as a child of the procexp.exe process.

This is the process name for Process Explorer.

This makes sense since Process Explorer was

a process in charge of starting it again after we terminated it.

But what about the Suspend option?

Instead of killing a process,

you can use this option to suspend it and potentially continue it at a later time.

If we right-click, suspend the process,

we'll see that in the CPU column,

the process explorer output,

the word suspended appears.

While a process is suspended,

it doesn't consume the resources it did when it was active.

We can kick it off again by right-clicking and selecting the Resume option.

Process Explorer can do a lot,

and we'll take a look at some of

the monitoring information it can give us in an upcoming lesson.

We won't get into the details of all its features though.

So, if you're curious, you can check out the documentation on Microsoft's website.

We put a link to it for you and the supplementary reading.
