Question

我有几千个文件名分隔：

Last, First-000000-Title-MonYYYY.pdf

Probem 1：某些文件符合6位数约定，而其他文件需要前导零以保持一致性。

问题2：有些名称是用破折号输入的（有问题的是分隔符）需要连接起来： Last-Last，First＆gt; LastLast，First

我能够为每个文件执行简单的Rename-Item函数，但是无法创建更广泛的Get-ChildItem函数，同时考虑到文件名的多次迭代以生成一致输出

为入门级问题道歉，但我似乎无法将所需的功能连贯地汇总在一起。

根据您的解释：

Set-Location -Path "C:\path" # replace this with actual path to where the files are

$cFiles = Get-ChildItem -Filter "*.pdf" # Getting all PDFs in the folder

foreach ($oFile in $cFiles) {
    $sName = $oFile.Name
    # This regex captures 1-5 digits number between two dashes.
    $sPattern = '(?:(?<=-))(\d{1,5})(?:(?=-))'
    if ($sName -match $sPattern) {
        # Extracting number.
        [UInt32]$iNumber = $sName -replace (".*" + $sPattern + ".*"), '$1'
        # Padding number with zeros.
        $sNumber = "{0:D6}" -f $iNumber
        # Updating filename string.
        $sName = $sName -replace $sPattern, $sNumber
    } else {
        # This regex captures 6 digits number between two dashes.
        $sPattern = '.*-(\d{6})-.*'
        # Extracting number.
        $sNumber = $sName -replace $sPattern, '$1'
    }

    # Splitting filename string on 6 digits number.
    $cParts = $sName -split $sNumber
    # Removing dashes from first/last names and re-assembling filename string.
    $sName = ($cParts[0] -replace '-') + '-' + $sNumber + $cParts[1]

    Rename-Item -Path $oFile.Name -NewName $sName
}

测试了以下示例：

Last, First-000000-Title-Jan1900.pdf
One-Two, Three-123-Title-Feb2000.pdf
Four, Five-Six-456-Title-Mar2010.pdf
Seven-Eight, Nine-Ten-7890-Title-Sep2012.pdf

如果有更复杂的案例，可能无效。

使用Rename-Item制作数字标识符＆amp;名称一致
