有没有一个命令可以让我重命名一个只有一定数量的数字的目录？

Question

我有一个目录，其中包含许多子目录。基本上，我想知道是否有一种方法可以删除文件夹中的所有单词，而只保留文件夹名称中的数字，这些数字以一系列 6 的形式排列在一起。

例如：

之前的文件夹名->示例1 123456

之后的文件夹名 -> 123456

我能够使用过滤器使用 powershell 删除空格、字符和单个数字。看起来像这样。

这在我前一阵子尝试时不起作用，因为当我尝试删除单个数字时，它会留下空白文件夹或只有一个数字的文件夹。我想知道是否有人会足够亲切地帮助我，如果我想学习，朝着正确的方向前进会很棒。

谢谢！

Answer 1

这将检查 'C:\TestFolder' 子文件夹的 6 位数名称，如果匹配，则将文件夹重命名为这 6 位数（使用 -match 运算符时包含在自动变量 $Matches 中）

Get-ChildItem -Path 'C:\TestFolder' -Directory | 
    Where-Object { $_.Name -match '\d{6}' } | 
    Rename-Item -NewName { $Matches.Values[0] } -WhatIf

Answer 2

如果我理解正确，您可以使用正则表达式来匹配六个连续数字的模式，而不是尝试一次处理每个非数字字符。

例如

$Values = @('a123456', 'a 123412', '21 413 512312')

$Values | ForEach-Object {
    if($_ -match '\d{6}'){
        $Matches[0]
    }
}

$Matches 自动存储 -match 的结果。

\d{6} 表示六个连续的数字。

找到匹配项后，您需要做的就是处理找不到六位数时发生的情况，然后重命名项目。
