Example 1

C:\PS>write-host "no newline test " -nonewline

no newline test C:\PS>


Description
-----------
This command displays the input to the console, but because of the NoNewline parameter, the output is followed directly by the prompt.






Example 2

C:\PS>write-host (2,4,6,8,10,12) -Separator ", +2= "

2, +2= 4, +2= 6, +2= 8, +2= 10, +2= 12


Description
-----------
This command displays the even numbers from 2 through 12. The Separator parameter is used to add the string , +2= (comma, space, +, 2, =, space).






Example 3

C:\PS>write-host (2,4,6,8,10,12) -Separator ", -> " -foregroundcolor DarkGreen -backgroundcolor white

This command displays the even numbers from 2 through 12. It uses the ForegroundColor parameter to output dark green text and the BackgroundColor parameter to display a white background.






Example 4

C:\PS>write-host "Red on white text." -ForegroundColor red -BackgroundColor white

Red on white text.


Description
-----------
This command displays the string "Red on white text." The text is red, as defined by the ForegroundColor parameter. The background is white, as defined by the BackgroundColor parameter.
