SharePoint and PowerShell

I have realised the importance and power of PowerShell and hence thought about sharing.

These days I am working very deeply with PowerShell in SharePoint.

Sending an email using PowerShell...

Function SendMail
{
  $smtpServer = "your SMTP server name"
  $logFileName= "C:\test.txt"
  $att = new-object Net.Mail.Attachment($logFileName)
  $msg = new-object Net.Mail.MailMessage
  $smtp = new-object Net.Mail.SmtpClient($smtpServer)
  $msg.From ="test@gmail.com"
  $msg.To.Add("he@gmail.com")
  $msg.To.Add("she@gmail.com")
  $msg.Subject = "Test Mail"
  $msg.Body = "This is a test email.
  $msg.Attachments.Add($att)
  $smtp.Send($msg)
  $att.Dispose()
}

Power of SPQuery Object in SharePoint....

$spSiteUrl = "http://webapplication"
$spWeb= Get-SPWeb -Identity $spSiteUrl

Function EmptySPList
{ Param($listname)
  IF($spWeb -ne $null)
  {
   $list = $spWeb.Lists.TryGetList($listname)
   $caml=""
   $query=new-object Microsoft.SharePoint.SPQuery
   $query.ViewAttributes = "Scope='Recursive'"
   $query.Query=$caml
   $items=$list.GetItems($query)
   $items | % { $list.GetItemById($_.Id).Delete()  }
   Write-Host "Items from list '" $listname "' are deleted successfully." -ForegroundColor Green
  }}

Function FindSpecificSPListItems
{
 Param($list)
 $dateFrom=[Microsoft.SharePoint.Utilities.SPUtility]::CreateISO8601DateTimeFromSystemDateTime([DateTime]::Today)
 $dateTo=[Microsoft.SharePoint.Utilities.SPUtility]::CreateISO8601DateTimeFromSystemDateTime([DateTime]::Today.AddMonths(-3))
 $spQuery = New-Object Microsoft.SharePoint.SPQuery
 $spQuery.ViewAttributes = "Scope='Recursive'";
 $spQuery.RowLimit = 100
 $caml = '<Where><And><Leq><FieldRef Name="Date" /><Value  Type="DateTime">'+$dateFrom+'</Value></Leq><Geq><FieldRef Name="Date" /><Value Type="DateTime">'+$dateTo+'</Value></Geq></And></Where><OrderBy><FieldRef Name="Title" Ascending="True" /></OrderBy>'
 $spQuery.Query = $caml
 $listItems = $list.GetItems($spQuery)
 if($listItems -ne $null)
 {
  #do some stuff
 }}
