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 CommonParameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -WarningAction, -WarningVariable, -OutBuffer -OutVariable.
Write-host (and Write-Warning) write only to the host/screen. To also have the output passed to the success pipeline, use Write-Output.
Write-host by default adds a single space separator between items, to remove that you must specify an empty string '' as the separator.

PS C:\> write-host "The quick brown fox jumped" -foregroundcolor DarkGreen -backgroundcolor white

PS C:\> write-host $one $two -separator ''
