Compare 2 Image folders and copy the missing images
Hi Everyone,
often , we do take photos and store it in our external drives with same name or different name.
ex: we have inserted the Camera memory card in our system and copy it to our specific drive or to other external drive. some time though images are same, file names might be different. we can do the image comparison using powershell hash. below is the script for this.
$Source= “C:\Users\Chaitanya\Pictures\Camera Roll”
$Destination = “C:\Users\Chaitanya\Pictures\Test\Testing”
$Destinationobj =get-childitem -Path $Destination -Recurse
$DestinationobjCount=$Destinationobj.Count
$DestObjArr=@();
$Destinationobj| ForEach-Object {
$DestinationobjCount–;
$DestHash=$null
$DestFileName = $_.Name
$DestFilePath = $_.FullName
$DestHash = Get-FileHash -Path $DestFilePath -Algorithm MD5
Write-Host “Creating Hash for Destination Image name $($DestFileName) and Current Image Count is : $($DestinationobjCount) ” -ForegroundColor cyan
if($DestHash)
{
$DestObjArr+=[pscustomobject]@{DestFileName=$DestFileName; DestFileHash=$($DestHash).Hash;}
}
}
$SourceObj =get-childitem -Path $Source -Recurse
$SourceObjCount=$SourceObj.Count
$SourceObj| ForEach-Object {
$SourceObjCount–;
$SrcFile = $_.FullName
$SRCFileName = $_.Name
$DestFilepath =$Destination+”\”+$SRCFileName
Write-Host “Creating Hash for Source Image name $($SRCFileName) and Current Image Count is : $($SourceObjCount)” -ForegroundColor cyan
$SrcHash = Get-FileHash -Path $SrcFile -Algorithm MD5
if ($SrcHash)
{
Write-Host “Checking the Destination Hash for Source File Name : $($SRCFileName) ” -ForegroundColor Cyan
if ($DestObjArr | Where-Object {$_.DestFileHash -eq $($SrcHash).Hash})
{
Write-Host “Hash Exists for Source Image Name $($SRCFileName)” -ForegroundColor DarkYellow
}
else
{
Write-Warning “Hash does Not Exists for Source Image Name :$($SRCFileName), Copying ..”
if (!(Test-Path $DestFilepath))
{
Write-Host “File Name not exists, Copying started for Source Image Name :$($SRCFileName)” -ForegroundColor White
Copy-Item $SrcFile -Destination $DestFilepath
}
else
{
Write-Host “File Name exists, create new name, Copying started for Source Image Name :$($SRCFileName)” -ForegroundColor Magenta
[string]$logdate= Get-Date -Format “yyyyMMddHHssmm”
$DestFilepath =$Destination+”\”+$SRCFileName.Split(“.”)[0]+ $($logdate)+”.”+$SRCFileName.Split(“.”)[1]
Copy-Item $SrcFile -Destination $DestFilepath
}
Write-Host “Copying complete for Source Image Name :$($SRCFileName)” -ForegroundColor Green
}
}
}
i hope with this your problem with the image saving in your external drives will be solved.
post your comments and let us your opinion on this.

Configure schedule task that runs every 5 minutes for N years
Hi all,
Here is the sample PowerShell script to configure schedule task that runs every 5 minutes for 3 years.
You can change the years , why did I not mentioned infinite time is because of some limitation that I had explained in the other article.
Script:
$mycredentials = Get-Credential
Invoke-Command -ComputerName “Server1”,”Server2” -Credential $mycredentials -ScriptBlock {
$dt= ([DateTime]::Now)
$timespan = $dt.AddYears(3) -$dt;
$Action = New-ScheduledTaskAction -Execute ‘powershell.exe’ -Argument ‘-command “D:\PS_Jobs\PS_Job1.ps1” -ExecutionPolicy RemoteSigned -NoProfile’
$Trigger = New-ScheduledTaskTrigger -Once -At 9am -RandomDelay (New-TimeSpan -Minutes 30) -RepetitionDuration $timespan -RepetitionInterval (New-TimeSpan -Minutes 60)
$Task = New-ScheduledTask -Action $Action -Trigger $Trigger -Settings (New-ScheduledTaskSettingsSet)
$Task | Register-ScheduledTask -TaskName ‘Job1 Task’
}

Convert datetime::Now value to specific format for comparison-Power Shell
Hi All,
How to convert datetime value to specific format for comparison
For get-date cmdlet, we have property called format , using that I can convert the date into specific format.
But for [datetime]::Now as it is c# static class, for that to convert the date time into specific format, you could use the toString method like below
$date = get-date -Format "yyyyMMddhhmm" – input value
$date2=([datetime]::Now).ToString("yyyyMMddhhmm") -comparing against time
if ( $date -eq $date2)
{
"yes"
}
else
{
"no"
}

Check Disk availability for Storage pool
