Write-Host PowerShell Cmdlet

Writes customized output to a host.

Write-Host
     [[-Object] <Object>]
     [-NoNewline]
     [-Separator <Object>]
     [-ForegroundColor <ConsoleColor>]
     [-BackgroundColor <ConsoleColor>]
     [<CommonParameters>]

The Write-Host cmdlet's primary purpose is to produce for-(host)-display-only output, such as printing colored text like when prompting the user for input in conjunction with Read-Host. Write-Host uses the ToString() method to write the output. By contrast, to output data to the pipeline, use Write-Output or implicit output.

Write-Host "no newline test " -NoNewline
Write-Host "second string"

no newline test second string
