#======================================================
# Usage: Updated by Lihua at 05/05/2009 zivsoft.com
# OutputHelp SqlServerCmdletSnapin100 SqlCmdletsFolder
# OutputHelp HelloWorldPSSnapin HelloFolder
# Output UnknownPSSnapIn UnknownCmdletsFolder
#======================================================
function OutputHelp{
$snapin=$Args[0] #the snapin that you will specified
#verify parameter
if($snapin -eq $null){
throw "The first parameter Snapin is null"
    }
$folder=$Args[1] #the folder where files will stored
$snapins = Get-PSSnapin -Name $snapin
if($snapins -eq $null){
#add pssnapin
        Add-PSSnapin $snapin
    }   
$d =  Get-Command -PSSnapin $snapin
#verify the existing snapin has the command-let
if($d -eq $null){
throw "The snapin $snapin has none cmdlets"
    }
"Total:" + $d.Count
$i = 0
#Verify the folder exists
if([System.IO.Directory]::Exists([AppDomain]::CurrentDomain.BaseDirectory.ToString() + $folder) -eq $false){
        md $folder
    }
$d | foreach -process{
$i++
"Printing" + $i
$cmdlet = $_.Name
$path = ".\$folder\"+$cmdlet + ".ps1"
        Get-Help -Examples $cmdlet > $path
    }
"Successfully"
}

7. 关闭（重启）远程计算机

#=================================
