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...

  1. i like how your file delete process is interactive. I have one similar but never considered the read-host component. Nice work.
