重命名文件现有文件名后将序列添加到文件名末尾的脚本

Question

我使用 ChatGPT 编写了一个脚本，将文件名的一部分从“SF78”重命名为“Medical”，并在文件名末尾添加序列 (1) 等。不幸的是，它并不是 100% 成功。该序列将添加到文件扩展名之后。

我尝试使用 $file.BaseName 来不包含扩展名，然后在加入 $file.basename、序列和文件扩展名后添加扩展名。似乎什么都不起作用。当我距离如此之近时，它必须是特定位置的最小设置，但就是无法正确设置。

这是脚本：

```
$folderPath = $filePath

$files = Get-ChildItem -Path $folderPath -File | Where-Object { $_.Name -match 'SF78' }

foreach ($file in $files) {
$originalName = $file
$newName = $originalName -replace 'SF78', 'MEDICAL'

# Check if a file with the new name already exists
$counter = 1
while (Test-Path (Join-Path -Path $folderPath -ChildPath $newName)) {
    $testName = $originalName -replace 'SF78', 'MEDICAL'
    $newName = (($testName, ($counter))  -join ' ') + $file.extension
    $counter++
}

# Rename the file
$newPath = Join-Path -Path $folderPath -ChildPath $newName
Rename-Item -Path $file.FullName -NewName $newName 
Write-Host "Renamed $($originalName) to $($newName)"
}
```

尝试使用这个脚本。我已经修改了

$folderPath = $filePath

$files = Get-ChildItem -Path $folderPath -File | Where-Object { $_.Name -match 'SF78' }

foreach ($file in $files) {
    $originalName = $file.Name
    $basename = $file.BaseName
    $extension = $file.Extension

    $newName = $basename -replace 'SF78', 'MEDICAL'

    # Check if a file with the new name already exists
    $counter = 1
    while (Test-Path (Join-Path -Path $folderPath -ChildPath "$newName$extension")) {
        $newName = "$basename ( $counter )"  # Add sequence within parentheses before extension
        $counter++
    }

    # Rename the file
    $newPath = Join-Path -Path $folderPath -ChildPath "$newName$extension"
    Rename-Item -Path $file.FullName -NewName $newPath
    Write-Host "Renamed $($originalName) to $newName"
}
