The logical evolution of the popular Windows command prompt (cmd.exe) is Windows PowerShell. It has new capabilities and features such as the use of interactive commands and Unix-style command base “cmdlets”. It is a powerful utility for Windows system administrators and interacts with SQL Server, Exchange or IIS. Another is to allow capabilities automate tasks and script execution with the *.

FormatSyntax of the commands in Powershell:
In any shell that we can find, the commands have a specific format so they can be interpreted correctly. As I said in the previous article, the commands in Powershell called “camlets “(command lets).
Normally a commandlet consists three parts.
- A verb.
- A name.
- One or more parameters (optional).
The verb and name are separated by the character ”dash” (-) and the parameters and arguments by the character “space” could be more or less like this:
