从照片集中识别最佳照片

Question

我从这个网站上借用了代码，它看起来对我作为摄影师很有帮助。由于我不知道PowerShell，我想问一下这段代码是否看起来不错。我不想错误地丢失我的照片。

$source_to_use_as_reference = "C:photosmytrip_to_hawaiBest"
$destination_to_copy =        "C:photosmytrip_to_hawaiBestBest_CR2"
$location_to_find_CR2_files = "C:photosmytrip_to_hawaiCR2"
# these are the codes to find CR2 files that matches with JPG files and copy
# them to new destination
cls
$count_all = 0 
$count_matches = 0 
$a = Get-ChildItem -Path $source_to_use_as_reference -Recurse -File
foreach ($item in $a) {
    $count_all += 1
    if ($item.Name -match "JPG") {
        $name_as_CR2 = $item.Name.Replace('JPG','CR2')
        $location_and_cr2_name = $location_to_find_CR2_files + $name_as_CR2
        if (Test-Path -Path $location_and_cr2_name ) {
            $destination_and_CR2_name = $destination_to_copy + $name_as_CR2
            if (Test-Path -Path  $destination_and_CR2_name) {
                Write-Output "already exists I skipped ... "   $destination_and_CR2_name 
            } else {
                $count_matches += 1
                Write-Host "I found it "  $destination_and_CR2_name
                Copy-Item -Path $location_and_cr2_name -Destination $destination_to_copy
            }
        } else {
        }
    }
}
Write-Output "$count_matches matches found and files copied to destination $destination_to_copy"

该脚本中没有任何险恶之处，它只是识别、计数并将 JPG 和 CR2 文件复制到第二个位置。
