New-Variable - Powershell 1.0 CmdLet

Microsoft Windows PowerShell is a command-line shell and scripting tool based on the Microsoft .NET Framework. It is designed for system administrators, engineers and developers to control and automate the administration of Windows and applications.

More than hundred command-line tools (so called "cmdlets") can be used to perform system administration tasks and Windows Management Instrumentation (WMI). These cmdlets are easy to use, with standard naming conventions and common parameters, and standard tools for piping, sorting, filtering, and formatting data and objects.


Create a new variable


       The name of the new variable(s).

   -value Object
       The value to assign to the variable, may be piped.
   -scope string
       The scope in which this alias is valid. 
       Valid values are "Global", "Local", "Private" or "Script", or a number 
       relative to the current scope ( 0 through the number of scopes, where 
       0 is the current scope and 1 is its parent). "Local" is the default.
       For more, type "get-help about_scope".

   -description string
       A description of the variable

   -option ScopedItemOptions
       Where the new variable should be visible/changeable:
       ReadOnly, Constant, Private or AllScope.

       Override restrictions as long as security is not compromised.
       Make a best attempt at setting the variable.

       Pass the object through the pipeline. By default, New-Variable 
       does not pass any objects through the pipeline.
       Describe what would happen if you executed the command without
       actually executing the command.
       Prompt for confirmation before executing the command.
       -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutVariable.
