Copy entire files from TFS to local using PowerShell

In this script I am going to show how we can copy all the files available under a specified path to your local machine

1. cls  
2.   
3. Write-Host "Enter source location "  // your tfs path
4. $sourceLocation = Read-Host  
5.   
6. $tfsCollectionUrl = New-Object System.URI($sourceLocation);  
7.   
8. Write-Host "Enter server path "  // tfs source location $/MyFirstProject/
9. $serverPath = Read-Host  
10.   
11. Write-Host "Enter local path to download"  // your local folder
12. $localPath = Read-Host  
13.   
14. [Microsoft.TeamFoundation.Client.TfsTeamProjectCollection] $tfsCollection = Get-TfsServer $tfsCollectionUrl  
15.   
16. $VersionControl = $tfsCollection.GetService([Microsoft.TeamFoundation.VersionControl.Client.VersionControlServer])  
17. $latest = [Microsoft.TeamFoundation.VersionControl.Client.VersionSpec]::Latest  
18. $recursionType = [Microsoft.TeamFoundation.VersionControl.Client.RecursionType]::Full     
19.   
20. try  
21. {  
22.     foreach ($item in $VersionControl.GetItems($serverPath, $latest,$recursionType).Items)  
23.  {  
24.     $target =   [io.path]::Combine($localPath,$item.ServerItem.Substring(2))  
25.     $exists=[System.IO.Directory]::Exists($target)  
26.  
27.    if($item.ItemType -eq "Folder" -and !$exists)  
28.    {  
29.        New-Item $target -Type Directory  
30.    }  
31.    if($item.ItemType -eq "File")  
32.    {  
33.       $item.DownloadFile($target)  
34.    }  
35.   }  
36. 
    
37. Write-Host "`n Successfully downloaded all the files to the target folder: " $localPath -ForegroundColor Green  
38. }  
39.     catch  
40.     {  
41.         $ErrorMessage = $_.Exception.Message  
42.         $FailedItem = $_.Exception.ItemName  
43.         Break  
44.     }  

PowerShell - Search XML by passing an input parameter

In this script I would like to show how we can perform XML search by passing an input parameter.
Sample xml file to work with the example

9.   <Age>29</Age>  
10.   <Location>Hyderabad</Location>  
11. </Employee>  
12. <Employee>  
13.   <Name>TestName3</Name>  
14.   <Age>45</Age>  
15.   <Location>Rajahmundry</Location>  
16. </Employee>

Powershell - Find all the application pools that are stopped in IIS and restart

This script is used to loop through all the application pools and will restart the application pools that are stopped

1. function RestartApplicationPool  
2. {  
3.     Clear-Host  
4.   
5.     $webapps = Get-WebApplication  
6.     [string] $list = @()  
7.       
8.     foreach ($WebAppPools in get-childitem IIS:\AppPools\)  
9.     {  
10.         $name = "IIS:\AppPools\" + $WebAppPools.name  
11.         $item = @{}  
12.    
13.         $item.WebAppName = $WebAppPools.name  
14.         $item.State = (Get-WebAppPoolState -Name $WebAppPools.name).Value  
15.   
16.         if($item.State -eq 'Stopped')  
17.         {  
18.             Start-WebAppPool -Name $WebAppPools.name  
19.             #$obj = New-Object PSObject -Property $item  
20.             $list += $WebAppPools.name  
21.             $list+=" and "  
22.               
23.         }  
24.     }  
25.     if($list.Length -gt 0)  
26.     {  
27.         $list = $list.Remove( $list.Length - 4, 4 )  
28.     }  
29.   
30.     if($list.Length -gt 0) {  
31.         Write-Host "Successfully restared the following " $list -ForegroundColor Green  
32.     }  
33.     else{  
34.         Write-Warning "No application pools found to restart"  
35.     }  
36. }  
37.   
38. RestartApplicationPool  

This is how it will display the result, displays the Application pool that it starts

10.     [string] $ConsonantsString  
11.     $StringLength = @()  
12.       
13.     $StringLength = $InputString.Length  
14.   
15.     for($i=0;$i -lt $StringLength;$i++)  
16.     {  
17.       
18.         if($InputString[$i] -eq "a" -or $InputString[$i] -eq "e" -or $InputString[$i] -eq "i" -or $InputString[$i] -eq "o" -or $InputString[$i] -eq "u")  
19.         {  
20.             $VowelString = $VowelString + $InputString[$i]  
21.         }  
22.         else  
23.         {  
24.             $ConsonantsString = $ConsonantsString + $InputString[$i]  
25.         }  
26.     }  
27.       
28.     Write-Host "`n Vowles are !" $VowelString -foregroundcolor "green"
