Over the last few years, I have been using PowerShell to assist in getting a lot of my day-to-day work done. This is especially more so since the environments IT works in are growing and having scripts do the work is much faster than using the GUI. The frustrating bit is I learn PowerShell based on what I read other IT professionals have done, I modify this for my needs at that time. But when I want to try something new for another task I get errors. These Errors are either Syntax errors or Parsing information that is not understood by the following command-let which in turn takes time to figure out what I am doing wrong.<\/p>\n\n\n\n

Thus it is time to spend some time and really gets to learn PowerShell. PowerShell is big and ties into many out-of-the-box applications within Microsoft. It has grown so far as to have 3rd party applications use PowerShell to manage their application\\services.<\/p>\n\n\n\n

What is Powershell?<\/h2>\n\n\n\n

PowerShell is a Modern command Shell that includes features from other popular shells. PowerShell is object Oriented meaning that it consists of Class and Object and can be used to simply gather information or configure systems based on a current environment\\system state. It allows for bulk automation of management of Systems.<\/p>\n\n\n\n

Class and Object<\/h3>\n\n\n\n

A class is a blueprint that is used when creating an Object. An Object is the specific details you receive back.

A simple example would be, All computers have a Serial Number which it can be identified by. We can call this Class PC_Information<\/strong>. When referring to a specific Computer you would get a Serial Number off 123456<\/strong>. This can be seen as the Object. If the PC_Information<\/strong> Class had a property call Make<\/strong>, the Object would have the same Property but the value would be specific to that Workstation.<\/p>\n\n\n\n

Basics of the Language<\/h2>\n\n\n\n

PowerShell consists of four sections. At its basic level it really only needs two of these Sections the Verb-Noun, combined it is known as a commandlet<\/strong>. It is case-insensitive, you can write it in all caps or all lower case, the output will be the same. PowerShell is a Natural Language meaning it is easily understandable for human reading. The four sections are as follows:<\/p>\n\n\n\n
