Windows PowerShell command on Get-command Write-Output

NAME

Write-Output

SYNOPSIS

Sends the specified objects to the next command in the pipeline. If the command is the last command in the pipeline, the objects are displayed in the console.

SYNTAX

Write-Output [-InputObject] [-NoEnumerate] []

DESCRIPTION

The Write-Output cmdlet sends the specified object down the pipeline to the next command. If the command is the

last command in the pipeline, the object is displayed in the console. Write-Output sends objects down the primary

pipeline, also known as the "output stream" or the "success pipeline." To send error objects down the error

pipeline, use Write-Error.

This cmdlet is typically used in scripts to display strings and other objects on the console. However, because the default behavior is to display the objects at the end of a pipeline, it is generally not necessary to use the

cmdlet. For instance, `Get-Process | Write-Output` is equivalent to `Get-Process`.

PARAMETERS

-InputObject

Specifies the objects to send down the pipeline. Enter a variable that contains the objects, or type a command or expression that gets the objects. Required? true Position? 0 Default value None Accept pipeline input? True (ByValue) Accept wildcard characters? false

-NoEnumerate []

By default, the Write-Output cmdlet always enumerates its output. The NoEnumerate parameter suppresses the

default behavior, and prevents Write-Output from enumerating output. The NoEnumerate parameter has no effect

on collections that were created by wrapping commands in parentheses, because the parentheses force enumeration. Required? false Position? named Default value False Accept pipeline input? False Accept wildcard characters? false This cmdlet supports the common parameters: Verbose, Debug, ErrorAction, ErrorVariable, WarningAction, WarningVariable, OutBuffer, PipelineVariable, and OutVariable. For more information, see about_CommonParameters (https:/go.microsoft.com/fwlink/?LinkID=113216).

INPUTS

System.Management.Automation.PSObject

You can pipe objects to Write-Output .

OUTPUTS

System.Management.Automation.PSObject

Write-Output returns the objects that are submitted as input.

NOTES

Example 1: Get objects and write them to the console

PS C:\> $P = Get-Process

PS C:\> Write-Output $P

PS C:\> $P

The first command gets processes running on the computer and stores them in the $P variable.

The second and third commands display the process objects in $P on the console.

Example 2: Pass output to another cmdlet

PS C:\> Write-Output "test output" | Get-Member

This command pipes the "test output" string to the Get-Member cmdlet, which displays the members of the

System.String class, demonstrating that the string was passed along the pipeline.

Example 3: Suppress enumeration in output

PS C:\> Write-Output @(1,2,3) | measure

Count : 3 ...

PS C:\> Write-Output @(1,2,3) -NoEnumerate | measure

Count : 1 This command adds the NoEnumerate parameter to treat a collection or array as a single object through the pipeline.
