"Hello" PowerShell

Playing around with Windows PowerShell today. As usual, the first thing that people learn is the infamous "Hello World" program. So I tried scripting an array of string in PS (plus color!)

PS C:\> 0..15 | % {Write-Host -ForegroundColor $_ "HELLO Robert Jin!!!"}

Here's a breakdown of what's happening:

• 0..15 - This is a range operator with an array of numbers from 0 to 15
• Write-Host - Operator to print text to the screen
• -ForegroundColor - The color of the text
• $_ - The numeric value that is required for the the previous command (ForegroundColor)
• "<String>" - The string of text to display

ForegroundColor also have a few pre-set color schemes. Here's the list:

-ForegroundColor 0 = Black

-ForegroundColor 1 = Dark Blue

-ForegroundColor 2 = Dark Green

-ForegroundColor 3 = Dark Cyan

-ForegroundColor 4 = Dark Red

-ForegroundColor 5 = Dark Magenta

-ForegroundColor 6 = Dark Yellow (Not sure why this is showing as 'White')

-ForegroundColor 7 = Gray

-ForegroundColor 8 = Dark Gray

-ForegroundColor 9 = Blue

-ForegroundColor 10 = Green

-ForegroundColor 11 = Cyan

-ForegroundColor 12 = Red

-ForegroundColor 13 = Magenta

-ForegroundColor 14 = Yellow

-ForegroundColor 15 = White

Well, that's it for now =)
