General PowerShell Scripting Guidelines. . Windows PowerShell cmdlet naming helps you learn. Chapter 5 Using PowerShell Scripts. Windows PowerShell is a command-line shell and scripting language designed especially for system administration. Its analogue in Linux is called as Bash. What Is PowerShell? Microsoft Confidential 2. Windows PowerShellâ„¢ includes an interactive prompt and a scripting environment. Commands are object-based.

Follow One of the most heavily touted new features of Windows Vista, Windows and Windows 7 has been the introduction of PowerShell, the new command line scripting environment Microsoft developed to help make life easier for Windows Administrators. But there's a problem. Windows Administrators around the Internet are looking at PowerShell with this deer-in-the-headlights look. They're afraid of it, because it's new, it's completely different from anything Windows has had before, and everyone around them is saying it's the best thing since Active Directory. I, like most Windows Administrators with little to no scripting experience, approached PowerShell with that icky-fingers feeling one gets when cleaning dead cockroaches off the floor. 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. Why PowerShell? Before we get into the groove and start doing things with PowerShell, it's important to understand how it was developed.

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. Cmdlets are the main way to interact with the CLI. In PowerShell, most cmdlets are written in C and comprised of instructions designed to perform a function that returns a.

NET object. Over cmdlets can be used in PowerShell. Remote Signed will allow you to run your own scripts but will stop unsigned scripts from other users. In PowerShell, a script is essentially a text file with a ps1 extension in its filename. Looking to create your own PowerShell scripts? Taking this onboard will help to decrease the learning curve you face when using PowerShell and decrease the amount of new commands that you have to learn. Nonetheless, Command Prompt experience can definitely help new users to come to grips with PowerShell and hit the ground running.

The command-line interface can conduct full database backups, file backups, and transaction log backups.

There are many ways to backup a database in PowerShell, but one of the simplest is to use the Backup-SqlDatabase command. The Get-Help command can be used to literally get help with any other PowerShell command. If you then see the server in question operating under a restricted policy, you can then implement the Set-ExecutionPolicy command to change it. This cmdlet can be directed by using specific service names or objects. This cmdlet allows you to build reports with tables and colour, which can help to visualize complex data.

Simply choose an object and add it to the command.

For example: You can then add your own colours and borders to refine its presentation. Every object has its own line or row within the CSV file. This command is primarily used to create spreadsheets and share data with external programs. It can be invoked either in the runtime environment or the automation scripts. No such features offer by command prompt. PowerShell considers them as objects.

So the output can be passed as an input to other cmdlets through the pipeline. The PowerShell is very advanced regarding features, capabilities and inner functioning.

Command prompt is very basic.

Applications of Powershell Today, PowerShell has become an ideal choice for IT administrators as it eases management operation and effort in large corporate networks. For example, let's assume that you are managing a large network which contains more than four hundred servers. Now you want to implement a new security solution. This security solution depends on a certain service which needs to run on those servers.

You can surely log in to each server and see if they have that service install and running or not. However, it certainly takes a lot of human errors as your staff needs to spend lots of time on this non-productive process. However, if you use PowerShell, then you could complete this task in just a few minutes. That's because the entire operation is done with a single script which gathers information about the services running on the servers. 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.
