The verbs describe what action the cmdlet is going to perform. PowerShell follows a Verb-Noun syntax, in which command names always start with verbs and have a dash in the middle and a noun at the end. PowerShell also includes cmdlets, which are compiled binaries that allow users to build the tools necessary for their scripts. For example, you can run commands to read files, ping computers and even remove registry keys. Much like other shells, PowerShell has binary commands to execute most actions. ĭid you know? Since 2016, PowerShell has been available on MacOS, Linux and other *nix operating systems.
The program was such a success during the three-year implementation at Windows that as of Windows 7, PowerShell became the default install on all Windows platforms. To solve this, he created a document outlining his plans for a program that could keep up with and possibly succeed the old command lines thus, PowerShell was born. In 2002, Jeffrey Snover, working for Microsoft at the time, knew that the command-line interface for Windows was not as capable as Linux, Microsoft’s competitor. It has two primary functions: a command-line shell that is similar to the windows command prompt (known as “cmd.exe”) and a robust scripting language that can be molded to automate practically anything and everything one might need. PowerShell was originally designed with “easy to understand” in mind. PowerShell is an open-source scripting language that helps tech pros who may not necessarily be familiar with software programming to design efficient scripts and tools to assist in their daily work tasks.
In this PowerShell tutorial, we will show you how to use the For loop, ForEach-Object loop, and the While, Do-While and Do-Until loops. Loops are essential in being able to automate mundane tasks that take up too much of your valuable time. One of the more difficult tasks of attempting automation is writing loops for your scripts. Being able to automate both simple and complex scripts is an invaluable asset to businesses, daily tasks and even recreational use. PowerShell is a great tool to use for programmers and nonprogrammers alike.
