Windows Powershell is often being compared with Unix Bash Shell. But it actually does more than what you may expect. Unlike its Unix counterpart, the PowerShell pipeline is an object pipeline; that is, the data passed between cmdlets are fully typed objects, rather than byte streams. A cmdlet, pronounced "command-let" is same as what you call "shell script" in Unix. So don’t get confused with cmdlets
I have read more reviews on Powershell and excited to see Powershell in action. I'm posting all my learning as I learn so it could be useful to everyone.

So Here is your first simple “Hello World” script:
PS C:\Documents and Settings\jagadish.g> Write-Host "Hello World"
Hello World
PS C:\Documents and Settings\jagadish.g>
Write-Host cmdlet is similar to echo in Unix. You can specify separator, background color, foreground color and more.
PS C:\Documents and Settings\jagadish.g> Write-Host (10,10,12)
10 10 12
PS C:\Documents and Settings\jagadish.g> Write-Host (10,10,12) -Separator "+"
10+10+12
PS C:\Documents and Settings\jagadish.g> Write-Host (10,10,12) -Separator "+" -ForegroundColor Green -BackgroundColor Black
10+10+12
PS C:\Documents and Settings\jagadish.g>
Now we will go through some simple cmdlets.
Get-Process
Gets the processes that are running on the local computer or a remote computer
PS C:\Documents and Settings\jagadish.g> Get-Process | Select-Object -First 3
