Out-Host | Taking on PowerShell one cmdlet at a time | Weekly Blog

Share this post:

This is a part of an on-going blog series written by Adam Gordon. Each week, Adam will walk you through a PowerShell command, showing you when and how to use each one. This week, Adam covers Out-Host.

When to use Out-Host?

The Out-Host cmdlet sends output to the PowerShell host for display. The host displays the output at the command line. Because Out-Host is the default, you don’t have to specify it unless you want to use its parameters.

Out-Host is automatically appended to every command that is executed. It passes the output of the pipeline to the host executing the command. Out-Host ignores ANSI escape sequences.

The escape sequences are handled by the host. Out-Host passes ANSI escape sequences to the host without trying to interpret or change them.

What version of PowerShell am I using for this blog?

Get the PowerShell Version from your machine:

$PSVersionTable

This command shows you the PowerShell version information on your machine.

How to use Out-Host?

Display output one page at a time:

Get-Process | Out-Host -Paging

Get-Process gets the system processes and sends the objects down the pipeline. Out-Host uses the –Paging parameter to display one page of data at a time.

Use a variable as input:

$io = Get-History

Out-Host -InputObject $io

Get-History gets the PowerShell session’s history, and stores the objects in the $io variable. Out-Host uses the -InputObject parameter to specify the $io variable and displays the history.
