Windows PowerShell is a valuable tool for automating activities and simplifies configuration. It can automate any task in the Windows platform, such as Active Directory and Exchange. It’s no surprise that PowerShell has become a popular tool among windows users and sysadmins.
PowerShell expert by following these steps:
- Understanding of PowerShell language and ability to use it: Knowledge of PowerShell is a must and should also be able to use it. Along with this, an understanding of core concepts like objects, cmdlets, and pipelines. It’ll be a plus if you know the core approaches to discovery, such as Get-Help, Get-Module, Get-Command, Get-Member. You must understand how each feature works and how to use it in your scripts. PowerShell’s internal architecture is also nearly expected.
- Core Windows Features:To be a PowerShell expert, you must be able to apply your talents to Windows. You must know SMB (SMB3 SOFS, Cluster and Hyper-Converged S2D), AD and GPO, Hyper-V, Containers and Docker, File/Disk Storage, IP/TCP Networking, Task Scheduler, PLA, and many more. Utilize Azure because enterprises are increasingly going to the cloud; understanding Azure (or AWS) is a valuable skill. You should be able to create IaaS objects in the cloud with Azure, such as virtual machines, websites, and virtual networks.
- Knowledge of .NET Framework:PowerShell is developed on top of .NET, and its cmdlets rely on it. For example, Get-Process calls [System.Diagnostics.Process]:: GetProcesses(). Also called a static method [GetProcesses()] on a .NET Class [System.Diagnostics.Process]. You must know the architecture of .NET [BCL, CLR, IL, .NET Security, JIT Compilation, and many more]. The.NET Framework has features for which no cmdlets exist. For example, there are several.NET classes that are useful for localization. Clock types, Time zones, DST/ST, and other variables are all accessible via a method call and hence simple to use if you know-how.
- functionality of PowerShell modules:Cmdlets come in modules, and you can create your own. JEA and DSC both leverage modules. You should understand where modules are maintained, how PowerShell locates them, how the Module cache is built, and what is a manifest.
- C# and how to convert it to PowerShell: There are many great examples of further obscure tasks written in C#. You should be able to read C# well enough to understand how the code works and assemble small bits into a working PowerShell script. It’s also beneficial to know sufficient VB.NET to convert it to PowerShell.
- Master Remoting: This is a broad topic in the world of technology. You should be familiar with the PowerShell Remoting stack (SOAP, PSRM, and WinRM), as well as how endpoints function and how to establish a restricted endpoint.
- WMI and WMI Objects: WMI is a real feast of administrative goodies, some of which aren’t found anywhere else. You must know how to make and operate WMI objects by utilizing WMI and CIM cmdlets. You should be able to invoke methods, understand WQL, and trap WMI events. Also, be familiar with both cmdlet sets and when to utilize them.
- Understand how to use JEA:Another name for it is Just Enough Administration. It’s a useful feature that allows you to grant delegated rights for only the required tasks for their job. PowerShell is a highly useful security feature that is appealing to large and distributed corporations.
- COM and COM Objects: COM is used in various applications. The COM interop features in PowerShell can be used to automate each of the Microsoft Office applications. The Performance Alerting and Logging subsystem use the COM interface. In order to specify PLA data collector sets, you utilize PowerShell’s New-Object cmdlet to create a COM object.
- Know how to implement DSC:DSC is an excellent tool for configuring hosts and ensuring that they remain configured. You must understand setting up DSC pull servers (Web and SMB), DSC resources, and DSC report and error login. You should also be familiar with how DSC resource’s function and how to create your own.
Apart from the above list, the following are the additional points one should also know of:
- Knowledge of XML:Features like Task Scheduler use the XML. You should be able to use Windows’ XML as well as manage the DOM and XML documents. Also, XPath is a helpful skill. For example, Reports are created by the FSRM, and the report format can’t be changed. However, the FSRM also generates XML files containing the report’s raw data, which you can prepare as needed. For default object formatting, PowerShell also uses XML. You can modify the way PowerShell formats objects by customizing them.
- Know how to manage Azure: You should be familiar with Azure (or another cloud vendor’s) infrastructure features, such as content distribution, storage, virtual networks, and virtual machines.
- Be qualified in Windows Troubleshooting:There are several helpful PowerShell modules for troubleshooting, especially network troubleshooting. To a PowerShell expert, these tools are second nature. And in order to be a successful troubleshooter, you must first grasp the problem. It’s also crucial to understand how to make the most of the data in the event logs.
- Finally, be familiar with Microsoft docs.
So, these are the steps you must know to become a successful PowerShell Expert.
