Write a string to the display, optionally customizing the output. Output can be to any host but is typically the console screen.
Syntax Write-Host [[-object] Object] [-noNewLine] [-separator Object] [-foregroundcolor ConsoleColor] [-backgroundColor ConsoleColor] [CommonParameters] Key -object Object Object to display, typically a string. -noNewLine Do not end with a newline character. -separator String to output between objects displayed on the console. -foregroundcolor ConsoleColor The text color -backgroundcolor ConsoleColor Background color ConsoleColors: Black, DarkBlue, DarkGreen, DarkCyan, DarkRed, DarkMagenta, DarkYellow, Gray, DarkGray, Blue, Green, Cyan, Red, Magenta, Yellow, White
Starting in PowerShell 5.0, Write-Host is a wrapper for Write-Information . You can now use Write-Host to emit output to the information stream, but the $InformationPreference preference variable and InformationAction common parameters do not affect Write-Host messages.
So in effect Write-Host is always set to Continue and will always display, unless stream 6 is redirected.
Standard PowerShell output will trim/wrap output lines to match the width of the parent console window -1
Write-Host bypasses this step and writes directly to stdout.
Write-host by default adds a single space separator between items, to remove that you must specify an empty string '' as the separator.
Running a function will display the text:
Test-function { Write-host "here is some text" }
Test-function
If we assign the function to a variable, the text is still displayed:
$result = Test-function
If we assign the function to a variable, the text is still displayed:
$result = Test-function 6>$null
Display text in specific colours:
PS C:\> write-host "The quick brown fox jumped" -foregroundcolor DarkGreen -backgroundcolor white
PS C:\> Write-Host -ForeGroundColor Red "some text in red" -nonewline
Display several variables concatenated together with no separation character:
PS C:\> write-host $one $two -separator ''
