When Microsoft first released PowerShell many simply saw it as an updated version of VBScript. However, Microsoft loaded it with power, and made the decision that it would be the technology to be used to administer all of their products. Over time modules came out for Exchange, SQL Server, Active Directory, and other environments. Other companies who sold software to run on Windows servers saw the advantages of PowerShell for administration of their software, and many have started to release PowerShell modules too.
Now if you look at listings of skills companies are looking for when searching for new employees PowerShell is showing up as one of the prominent required or strongly desired skills. Knowledge of PowerShell could be the deciding factor on if you land that next job, or the promotion to a better position in your current company.
This course is designed to teach you the fundamentals of the PowerShell environment. It will lay the groundwork and foundation for more advanced PowerShell skills. You will learn what a PowerShell cmdlet is, and how much power you will have at your fingertips. You will learn about the object oriented nature of PowerShell and how to leverage that to be a true power user or power administrator.
When you are learning a new skill on a computer you have the possibility of messing something up on the computer. A solid solution to keep from having issues on your workstation is to install a virtual computer. The process is simple and straight forward. You will install a hypervisor, in our case Oracle VirtualBox, and then install the guest operating system.
Installing a guest computer is no different than installing an operating system on a physical computer. The steps are exactly the same. This video will walk you through both the installation of VirtualBox and Windows 10.
Here you will find detailed information on the virtual environment. This lecture goes into more detail about different hypervisors. It also discusses how to back up a virtual computer. This is exceptionally good to do when you are getting ready to do something you might want to roll back.
Everyone is familiar with the graphical user interface, or GUI environment that you use for a Mac or Windows. However, most people are unfamiliar with a shell environment. The command line, or non-GUI, environment is not used by nearly as many people. For a long time Windows administration was all done in the GUI. However, the shell is where a power user, or power administrator will do most of their work. This is now as true in Windows as it is in Linux.
This lecture will introduce you to what a shell environment is, and show examples for both Windows and Linux. You will also see that the command prompt window and the PowerShell console are different beasts too.
Some might think that PowerShell and the command prompt are the same thing. However, as we discuss some of the different cmdlets that are available and what they can do you will quickly see that there is much more to PowerShell then simply a different version of command.com for you to use. This short lesson will expose you to some cmdlets to work with processes, services, and even Active Directory.
There are two different environments that are native to Windows for running PowerShell. These are the PowerShell console and the ISE or integrated scripting environment. They each have their advantages, and this lecture will cover the main differences between the two.
In this lesson you will learn how PowerShell is the new direction for Microsoft for administration of both the operating system, and applications that run on Windows.
The help system is powerful in PowerShell. But you need to update it before you will have full access. This lesson shows you how to update the help system, and also use wild card searches to find cmdlets to get the job done.
It is one thing to say just ask the help system, it is another to be able to figure out what you need. But the help output is not as cryptic as you might think. Once we take a little time in this lecture you will be able to easily get your answer. The help system is actually very informative once you learn how to read the output.
We are all familiar with using Google to find information. But the help system in PowerShell can be an even faster resource. There are a number of tricks to learn how to do things in PowerShell from PowerShell itself. This lesson will help you master the help system.
Short quiz on the help system
Not only does the help system provide the syntax on how to run commands, and listings of the parameters for commands. It also has a substantial set of tutorials called about files that will help you gain in depth knowledge about many PowerShell topics. This lesson shows you those topics and how to access them.
Learning the basic structure of PowerShell commands will help you to both find the cmdlets you need to use and how to make them do what you want. This lesson will help you learn the basics of PowerShell cmdlets.
I regularly joke with people that I went into computers because I am lazy. I may not actually be lazy, but I love to be efficient. So I don't want to type more than I need to when I try to get something done. PowerShell has aliases that are shorter versions of cmdlets that you can use to reduce how much you need to type at the prompt. This lesson will teach you how to find out about those aliases.
This quiz is on PowerShell command structure and on aliases to those commands. Hint: Remember the help system, and that cmdlet for aliases from the lectures.
This lesson is a quick overview of cmdlet structure and also on aliases and how to find them.
PowerShell is much more than a simple command prompt. With that said, sometimes you will need to move around the file system and perform file management tasks. The PSProvider allows access to the file system. It is a bit different than at the command prompt, but will also give you a lot more power too.
The PSProvider system in PowerShell goes well beyond access to the file system. You can access a number of different systems on the computer in a similar manner as the file system. This lesson shows how to access the registry using the PSProvider. The way this works for the registry is the same as you would use for other PSProvider "drives" like the Active Directory PSProvider.
Most programmers are familiar with object oriented design. But for many others the words sound scary. But the concepts are actually quite easy to comprehend. This short little lesson will help you to understand what object oriented really means.
Now that we have the basics of what object oriented mean we have a lesson to make use of that knowledge. This lesson will start to move through cmdlets and their output and learn the power of being object oriented.
Because of the object oriented nature of PowerShell we can easily manipulate the data we are gathering so that we can more easily understand it. In this lesson you will learn how to sort the output of cmdlets with sort-object so that you can put some order to life.
It is typical that any time we run commands on a computer we will only get a subset of the data available from a command. This is also true of PowerShell cmdlets. The select-object command will allow you to expose any of the properties of objects cmdlets access.
A short quiz on the selecting objects cmdlet. Feel free to use the Get-Help cmdlet in PowerShell to assist in this.
Using sort-object, where-object, and select-object are powerful tools. But we run the risk of shooting ourselves in the proverbial foot if we are not taking care of the order that we put commands into the computer. You could easily remove a property too early, before you need to use it to sort or something. This lesson talks about how information flows through the pipeline, and things to consider as you structure your commands.
