Media, Inc. Windows Powershell Cookbook, the image of a box tortoise, and related trade Invoke a PowerShell Command or Script from Outside PowerShell. The name came from a book written by Leibniz called “Monadologie.” It explained that reality is composed of fundamental elements (Monades), which are all. Windows PowerShell 2 For Dummies explains how to deal with each and clues you in on creating, running, and looping scripts — and much more.
Scripting, for me, was always one of those things that just made me shiver and made my brain want to crawl out the back of my head and hide under a box in the corner. Then I got a new job and the first thing my new boss asked me to do was solve a number of problems that could only be done with PowerShell. So I had to learn and I had to do it fast.
I looked around for some good resources and found plenty. The sad thing was that they all seemed to be written by and for people who had a lot more experience than I did. So I just decided to use my talent for figuring things out on my own and dove in.
Advantages of using PowerShell script
Why PowerShell? Before we get into the groove and start doing things with PowerShell, it's important to understand how it was developed. Almost all system administrators know that a lot of the work they do is very repetitive.
You have to add users, remove users, create and delete mailboxes, and do all sorts of mundane tasks that don't take a great deal of skill to do. Well, at least, if you're doing it the hard way. The idea behind scripting is to do more in less time. Without a script, adding users to an Active Directory environment can take hours.
With a script, you can do the same task in just the time it takes to write the script and run it. Ever since the days of Windows , scripting was limited to somewhat long and occasionally complex scripts written in a cut down version of Visual Basic called VBScript. The only other option available to system administrators was Batch Scripting. While VBScript was a fairly functional programming language capable of doing pretty much anything you wanted to do in an environment, Batch Scripts were limited to pre-built commands that were supplied by Microsoft or picked up from third party developers.
Once you learned a few of the commands you needed to develop Batch Scripts, you could make great use of it.

VBScript, on the other hand, required knowledge of some complex and often very unintuitive programming concepts. It took a lot longer to learn VBScript, which meant that a lot of time inside and outside of work had to be devoted to learning the language.
In addition, writing workable VBScript code required a lot of troubleshooting and effort, and many times it takes longer to write the script than it takes to perform the task manually, so VBScript is typically limited to repetitive tasks that have to be done very often. In addition, there are numerous security concerns surrounding VBScript. Because of the chasm that existed between Batch Scripting and VBScript, a lot of systems administrators complained about the lack of a truly functional scripting language in Windows that was easy to use and learn.

As a result, Microsoft decided to develop an entirely new scripting system that took the functionality of VBScript and smashed it together with the softer learning curve associated with Batch scripting as a way to replace VBScript and. The result is PowerShell. PowerShell is, in essence, a Batch Scripting environment that rides on top of Microsoft's. NET Framework and is a fully-functional programming language. As you get deeper into the world of PowerShell, you will discover that it is almost infinitely flexible.
Tasks that could have taken hours or days just to script can be done with a few simple commands.
In fact, most administrative tasks can be done with a single, small script file that consists of fewer than 10 lines of code. Some things, like importing users as mentioned earlier, can be done with a simple two line script.
The end result is that tasks that used to take hours can now be done in minutes. Of course, before you can really get anything out of PowerShell, you have to start learning it. Luckily, it isn't hard to learn. You just have to hold your breath, get ready, and dive right in the way I did. Diving In Head First The biggest mistake that beginners make with PowerShell is to approach it like every other scripting language. You know, starting out with cute little scripts that scream "Hello World" on the monitor and little else.
But what so many people who just give up on PowerShell realize is that it does not have to be approached as a scripting language.
In fact, if you really want to avoid the scripting heeby-jeebies altogether, PowerShell can be treated just like our old friend the command prompt. And you'll still be able to do a lot of really powerful administration things with it. So the very first thing you want to learn about PowerShell is the cmdlet. Okay, actually, the first thing you need to know is how to start PowerShell. The other way to start powershell is to double-click a.
But getting back to it, cmdlets Commandlets, if you wish , are self contained scripts that require only that they be called like a command in the command shell. For instance, if you want to see the date, just type get-date.
Or if you want to see which services are running and which aren't, type get-service. To get a list of cmdlets that you can use in PowerShell, type get-command Or go here: I should note at this point that there are additional cmdlets available for use with Active Directory and Exchange, but I won't go into depth with those.
Getting cmdlets to Work Together While it might be nice to be able to view the date or services in PowerShell, those really aren't things you can't do in good old cmd. The real power of PowerShell is its ability to basically squish cmdlets together to do different things. I've heard it compared to the old erector sets that kids used to play with before video games started melting the brains of yungins world wide.
How does this work? Through a PowerShell feature called Command Pipelining. By using the pipe " " character, we can have one cmdlet take input from another cmdlet to complete complex tasks with a single command. Let's start with a for-instance. For some very odd reason you wanted to start every single service on a specific computer. Normally, you'd have to open the services. With PowerShell, you need only smush together two cmdlets, get-service and start-service , by typing the following: I'm not going to tell you that starting every service on a computer is a good idea.
This is just an example of what you can do with PowerShell. I didn't say it was useful. I should also mention that a not every service on a computer will start with this, because some services won't start unless certain other requirements are met, and b services already started will be processed, too.
More advanced features of PowerShell and get-service will let you filter this command so it only starts services that aren't working.
If you are interested, see Example 5 of help get-services -examples. I will likely cover these advanced features in later articles, but it isn't important right now. Being able to see the date and time is great and all. But how about what time it is down to the nanosecond and beyond? How about how many days we are into the year? There's a way to do that, because each cmdlet that returns data only shows a small amount of the data that it actually captures.
Another cmdlet, called format-list or fl for short will pull and display all the data that a cmdlet retrieves in a formatted list on the screen. Interestingly, format-list does absolutely nothing if it isn't piped with the " " character - you can't format "nothing".
So, let's try something. Just for giggles, lets squish together that dinky little get-date cmdlet with format-list and see what happens: DateTime Date: Netwrix Auditor.
Netwrix Auditor for Active Directory. Netwrix Auditor for Azure AD. Netwrix Auditor for Office Netwrix Auditor for Windows File Servers.
Netwrix Auditor for EMC. Netwrix Auditor for NetApp. Netwrix Auditor for Windows Server.
Netwrix Auditor for Exchange. Netwrix Auditor for Oracle Database. Netwrix Auditor for VMware. Netwrix Auditor for SharePoint. Netwrix Auditor for Network Devices.
Go Up. PowerShell is an administrative tool that Microsoft provides to simplify system administration. It helps automate a wide range of tasks, such as Active Directory administration, user and permissions management, and reporting on security configurations.

Business Backup You can automatically backup servers and databases in your company; employees can also backup their PCs, laptops and MACs. The result is PowerShell. Summary Windows PowerShell is object-oriented automation engine and scripting language Powershell offers a well-integrated command-line experience for the operation system PowerShell first version 1. This is just an example of what you can do with PowerShell. In addition, Microsoft has published full documentation on each cmdlet on Technet; take a look at the additional references or just do a search for PowerShell cmdlets.
