Describes the operators that are supported by Windows PowerShell. 

	An operator is a language element that you can use in a command or
	expression. Windows PowerShell supports several types of operators to
	help you manipulate values.

  Arithmetic Operators
	Use arithmetic operators (+, -, *, /, %) to calculate values in a command
	or expression. With these operators, you can add, subtract, multiply, or
	divide values, and calculate the remainder (modulus) of a division 

	You can also use arithmetic operators with strings, arrays, and hash 
	tables. The addition operator concatenates elements. The multiplication
	operator returns the specified number of copies of each element.

	For more information, see about_Arithmetic_Operators. 

  Assignment Operators
	Use assignment operators (=, +=, -=, *=, /=, %=) to assign one or more
	values to variables, to change the values in a variable, and to append
	values to variables. You can also cast the variable as any Microsoft .NET
	Framework data type, such as string or DateTime, or Process variable.

	For more information, see about_Assignment_Operators.

  Comparison Operators
	Use comparison operators (-eq, -ne, -gt, -lt, -le, -ge) to compare values
	and test conditions. For example, you can compare two string values to 
	determine whether they are equal. 

	The comparison operators include the match operators (-match, -notmatch) 
	to find patterns using regular expressions; the replace operator 
	(-replace), which uses regular expressions to change input values; and 
	the like operators (-like, -notlike), which find patterns using wildcard 
	characters (*). 

	They also include the bitwise operators (-bAND, -bOR, -bXOR, -bNOT) to 
	manipulate the bit patterns in values.

	For more information, see about_Comparison_Operators 

  Logical Operators
	Use logical operators (-and, -or, -xor, -not, !) to connect conditional
	statements into a single complex conditional. For example, you can use a
	logical -and operator to create an object filter with two different 

	For more information, see about_Logical_Operators.

  Redirection Operators
	Use redirection operators (>, >>, 2>, 2>, and 2>&1) to send the output of
	a command or expression to a text file. The redirection operators work 
	like the Out-File cmdlet (without parameters) but they also let you 
	redirect error output to specified files. You can also use the Tee-Object
	cmdlet to redirect output.

	For more information, see about_Redirection.

  Split and Join Operators
	The -split and -join operators divide and combine substrings. The -split 
	operator splits a string into substrings. The -join operator concatenates
	multiple strings into a single string.

	For more information, see about_Split and about_Join.

  Type Operators
	Use the type operators (-is, -isnot, -as) to find or change the .NET 
	Framework type of an object. 

	For more information, see about_Type_Operators.

  Unary Operators
	Use unary operators to increment or decrement variables or object 
	properties and to set integers to positive or negative numbers. For 
	example, to increment the variable $a from 9 to 10, you type $a++.

  Special Operators
	Use special operators to perform tasks that cannot be performed by the 
	other types of operators. For example, special operators allow you to 
	perform operations such as running commands and changing a value's data 

	&  Call operator
		Description: Runs a command, script, or script block. Because the call 
		operator does not parse, it cannot interpret command parameters. The 
		call operator, also known as the "invocation operator, indicates that 
		the value it precedes is a command. This enables you to run commands 
		stored in variables and represented by strings. Examples:

			& "new cmdlet"
			$c = "get-executionpolicy"
			& $c

	. Property dereference operator
		Description: Accesses the properties and methods of an object. 


	. dot sourcing operator
		Description: Runs a script so that the items in the script are part 
		of the calling scope. For more information, see about_Scope. Example:

			. c:\scripts.sample.ps1

		Note: The dot (.) symbol is also used as the parent directory symbol, 
			as in this example:


			This command runs the sample.ps1 script, but not as part of the 
			calling scope.

	:: Static member operator
		Description: Calls the static properties operator and methods of a .NET
		Framework class. To find the static properties and methods of an 
		object, use the Static parameter of the Get-Member cmdlet. Example:


	.. Range operator
		Description: Represents the sequential integers in an integer array, 
		given an upper and lower boundary. Examples:

			foreach ($a in 1..$max) {write-host $a}

	-f Format operator
		Description: Formats strings by using the format method of string 
		objects. Enter the format string on the left side of the operator 
		and the objects to be formatted on the right side of the operator.

			C:\PS> "{0} {1,-10} {2:N}" -f 
			C:\PS> 1,"hello",[math]::pi
			1 hello 3.14

	$( ) Subexpression operator
		Description: Returns the result of one or more statements. For a 
		single result, returns a scalar. For multiple results, returns an 
		array. Examples:

			$($x * 23)
			$(Get-WMIObject win32_Directory)

	@( ) Array subexpression operator
		Description: Returns the result of one or more statements as an array. 
		If there is only one item, the array has only one member. Example:

			@(Get-WMIObject win32_logicalDisk)

	, operator
		Description: As a binary operator, the comma creates an array. As a 
		unary operator, the comma creates an array with one member. Place the
		comma before the member. Examples:

			$myArray = 1,2,3 
			$SingleArray = ,1
