Deleting temp files on a remote server

Question

_{Saturday, August 9, 2014 8:59 PM}

Hi

I am very new to scripting world. I have written a basic code which does the job of deleting temp files under the listed folder path on a remote server. But as I see this process is taking quite a long time to process. I am hoping to find an other way to fasten this. Is it possible to push a script to the remote system first and run that locally? If I am not wrong that would make it process faster. 

I would also ask you to help me formatting this raw code. I want to introduce a logging system to this. Also make it work for multiple servers by fetching the list of servers from a csv. Thanks a lot in advance!!!!!

Code:

param (

    [string]$ComputerName = $(throw "ComputerName(s) is required.")

)

Clear-Host

    foreach ($computer in $ComputerName.Split(" "))

    {

        if (Test-Connection -ComputerName $Computer -ErrorAction SilentlyContinue)

        {

            Write-host ("About to clean : "+$computer)

$disk = ([wmi]"\$Computer\root\cimv2:Win32_logicalDisk.DeviceID='c:'")

"$Computer C: has {0:#.00} GB free of {1:#.00} GB Total - Before Cleaning" -f ($disk.FreeSpace/1GB),($disk.Size/1GB) | write-output

Write-output "Cleaning is in progress, Please wait"

Remove-Item -Recurse -Force \$ComputerName\c$\temp\

Remove-Item -Recurse -Force \$ComputerName\c$\$Recycle.bin'\

Remove-Item -Recurse -Force -erroraction 'silentlycontinue' \$ComputerName\c$\Windows\Temp\

$disk = ([wmi]"\$Computer\root\cimv2:Win32_logicalDisk.DeviceID='c:'")

"$Computer C: has {0:#.00} GB free of {1:#.00} GB Total - After Cleaning" -f ($disk.FreeSpace/1GB),($disk.Size/1GB) | write-output

}

}

Check out the Invoke-Command to remotely run code

To write a recursive function that steps through a folder structure with logging check out

batch file for checking every folder

Your code properly formatted without regard to syntax or correctness.

param ([string]$ComputerName = $(throw "ComputerName(s) is required."))

    Clear-Host
    foreach ($computer in $ComputerName.Split(" "))
    {
        if (Test-Connection -ComputerName $Computer -ErrorAction SilentlyContinue)
        {
            Write-host ("About to clean : "+$computer)
            $disk = ([wmi]"\\$Computer\root\cimv2:Win32_logicalDisk.DeviceID='c:'")
            "$Computer C: has {0:#.00} GB free of {1:#.00} GB Total - Before Cleaning" -f ($disk.FreeSpace/1GB),($disk.Size/1GB) | write-output

            Write-output "Cleaning is in progress, Please wait"
            
            Remove-Item -Recurse -Force \\$ComputerName\c$\temp\*
            Remove-Item -Recurse -Force \\$ComputerName\c$\'$Recycle.bin'\*
            Remove-Item -Recurse -Force -erroraction 'silentlycontinue' \\$ComputerName\c$\Windows\Temp\*
            $disk = ([wmi]"\\$Computer\root\cimv2:Win32_logicalDisk.DeviceID='c:'")
            "$Computer C: has {0:#.00} GB free of {1:#.00} GB Total - After Cleaning" -f ($disk.FreeSpace/1GB),($disk.Size/1GB) | write-output
        }
    }

To import a CSV file, we'll assume a csv file (C:\Computers.csv) like this

ComputerName,IPAddress
Computer1, 192.168.0.1
Computer2, 192.168.0.2

To step through the csv file and call a function with the contents as parameters

$csv = Import-CSV -Path "C:\Computers.csv"
ForEach($Line in $csv){
    $ComputerName=$Line.ComputerName
    $IPAddress=$Line.IPAddress
    Test-Function -ComputerName $ComputerName -IPAddress $IPAddress
}

Hope this helps
