Write Output - PowerShell

Overview

Write-Output is a fundamental command in PowerShell that allows users to output text or objects to the console or a file. It is used for printing messages, debugging information, and displaying results in a clear and organized manner.

Syntax

Write-Output [-InputObject] <object[]>

Parameters

| Parameter | Description |
|—|—|
| -InputObject | Specifies the objects to output. If not specified, the current pipeline object is used. |

Options/Flags

None.

Examples

Simple Output

Write-Output "Hello, world!"

Outputting Multiple Objects

Write-Output 1, 2, 3, "Hello", "World"

Outputting Formatted Objects

$person = New-Object -TypeName PSObject -Property @{
    Name = "John Doe"
    Age = 30
}
Write-Output $person

Common Issues

Output Truncation

By default, Write-Output truncates long lines to 1024 characters. To disable this, use $MaximumLineLength = Unlimited.

Excessive Output

If the pipeline produces too much output, use Out-Null to suppress it:

Get-Process | Out-Null

Integration

Write-Output can be used with other commands to create complex output formats:

Get-Service | Format-List -Property Name, Status | Write-Output

Related Commands

• Write-Host: Outputs text directly to the console without line breaks.
• Format-Table: Outputs objects in a tabular format.
• ConvertTo-Html: Outputs objects as HTML.
