Basic Windows Administration through Powershell

Hi Guys,

In the previous blog I took you through PowerShell basics We know that PowerShell to works with different modules like SQL server, Active Directory, Windows Administration, IIS, etc. In this blog I shall be updating a few scripts I've used. You may modify the same as per your environment.
You will be able to find many such scripts online and under http://powershell.com

1.Deleting Files older than Certain Date

#Folder from which files are to be deleted 

$filepath= "D:\"#Change the path based on your file location

#Accepting the number of days prior to which user wants to delete the files

$no_of_days = read-host "Enter the number of days(integer) prior to which backups should be delete "

$a=get-date

$a= $a.adddays(-$no_of_days)

#Confirming the date with the user

write-host "Do you want to delete files older than"$a"   Y/N"

$response=read-host

If ($response -eq "Y" -or $response -eq "y")

{

write-host " Deleting files from $filepath older than " $a

#Deleting files only

get-childitem $path -recurse | where-object {$_.mode -notmatch "d"} | where-object {$_.lastwritetime.date -lt $a} | ForEach-Object { Write-Host "Deleting "$_.FullName; Remove-Item $_.FullName;}

}

#Confirming shell closure

else

{

write-host "Execution cancelled to execute successfully pass the right parameters & hit Y/y. Any other input will be considered Invalid"

start-sleep -s 7} 

2. Pinging Multiple Servers

#Servername Text File

$filepath = "C:\Test.txt" #Change the path based on your file location

$Sname = Get-Content $filepath

#Running Loop for each servername in text file

foreach ($S in $Sname)

{

     #Checks if the server is pingable

     $StatusFlag =test-Connection -ComputerName $S -Count 1 -Quiet

     if ($StatusFlag) #If server is pingable dispaly source,destination & response time

      

       {

#Sends just one packet to the server and provides the response time 

        Test-Connection $S -count 1|select-object -Property @{Name="Source"; Expression = {$_.pscomputername}},@{Name="Destination"; Expression = {$_.address}},responsetime

       }

      else

                           

        {

         write-host "$S is inaccessible from $env:computername" -ForegroundColor Cyan

        }    

        

} 

3.Multiple Server Entire Directory Structure and File Copy 

# Directory from where the files and folder structure needs to be copied

$directorypath = 'C:\directory\*.*' #Change the path based on your file location

$servercount = read-host "Enter total number of servers for filecopy"

# Accepting servernames and inserting them in an Array

if ($servercount -gt 0)

{

#write-host "Enter the servernames"

$servers = @()

$i=0

 do

{

   $servers += read-host "Enter Server $($i+1)"

   $i++

}   while($i -lt $servercount)

   

   

    #Once servernames are accepted copy the entire direcorypath structure with the files to destination 

    Foreach ($s in $servers){

   

    #write-host "destination is " $s

     Copy-Item $directorypath -Destination "\\$s\C$\directory" -Recurse 

    #Change the Destination as per your requirement

     }

}

else

{

write-host "Total number of servers is 0 script exccution closed"

}

I'll update this with more scripts as and when tested and used. Until then keep learning and exploring...
