用于将文件移动到文件夹的Powershell脚本-如何从$newFolder中删除连字符？

根据文件名的第一部分，我有很多文件要归档到文件夹中。文件名->文件夹名由特定字符分隔：[-][，][和]。例如：

第一个文件名-2016-04.pdf 第二个文件名和另一个名称.mp3 第三.jpg 第四个文件名，2016.pdf

我希望生成的文件夹名称不包括[\s-][，\s][\sand\s]部分

这是我的脚本，除了文件夹名称包含我不想要的内容外，它是有效的，例如：

第一个文件夹名- 第四个文件名

我认为这与我的正则表达式匹配贪婪地包含连字符有关（特别是），但我不确定如何格式化查询和创建SUNBESQUENT文件夹名称

此外，用“######”（类似于进度指示器）注释掉的内容也不起作用。如果您有任何建议，请发表评论。我根本不是一个程序员

$OrigFolder = ".\"
$NewFolder = ".\_Sorted to Move"

# Orphans folder, where files that return null in the regex match will be moved
# Example: file "- title.mp4"
# will be moved to ".\Sorted\_Orphans" folder

$Orphans = '_Orphans' # Use the underscore to sort the folder to the top of the window

#### How to use an array of values for the delimiters in the regex instead of literals
#### My proposed code, but I am missing how o use the delims in the regex match
#### $delims = "\s-\s" ",\s"\s and\s"

# First count the number of files in the $OrigFolder directory
$numFiles = (Get-ChildItem -Path $OrigFolder).Count
$i=0

# Tell the user what will happen
clear-host;
Write-Host 'This script will copy ' $numFiles ' files from ' $OrigFolder ' to _Sorted to Move'

# Ask user to confirm the copy operation
Read-host -prompt 'Press enter to start copying the files'

# Regex to match filenames
$Regex = [regex]"(^\s*(.*?)\s*-)|(^\s*(.*?),)|(^\s*(.*?)\s*and\s)"

    # Loop through the $OrigFolder directory, skipping folders

    ForEach-Object {
        if($_.BaseName -match $Regex){

            #### Caluclate copy operation progress as a percentage
            #### [int]$percent = $i / $numFiles * 100

            # If first part of the file name is empty, move it to the '_Orphans' folder
            if(!$Matches[1]){
                $ChildPath = $Orphans
            } else {

非常感谢StackOverflow用户的帮助和我在上面拼凑的代码片段。

下面的正则表达式应该可以找到任何不需要的分隔符（使用非捕获组）：

现在，您所要做的就是使用

-用该正则表达式替换
，以摆脱它们：

if($_.BaseName -match $Regex)
{
    $ChildPath = $_.BaseName -replace $Regex

    # copy...
}

另外，请看一下：

如果未显示进度条，请检查
$ProgressPreference变量。如果该值设置为SilentlyContinue，
进度条不显示。有关Windows的详细信息，请参见
PowerShell首选项，请参阅关于首选项变量。参数
cmdlet的属性对应于ProgressRecord类的属性

下面是将my.pdf文件（杂志）移动到以杂志标题命名的子目录的完整脚本。感谢jisaak（Martin Brandl）帮助我解决regex问题。将“杂志”添加到新文件夹的解决方案位于第46/47行。对大多数人来说可能是显而易见的，但我花了一个小时才弄明白

我很想得到关于简化代码和修复缩进等方面的建议。我还不了解Powershell的风格，这是我的第一次尝试

我已经为我的多媒体文件和图片修改了脚本，你不知道这会为我节省多少时间。再次感谢你，马丁
 谢谢你的快速回复。我理解您试图向我展示的内容，但脚本无法将PDF移动到各个文件夹。相反，所有内容都被发送到“孤儿”文件夹，我想是因为正则表达式无法正确捕获名称？也许我把replace语句放错地方了……我把它放在了第31行“if（$\u.BaseName-match$Regex）”之后。谢谢你对write progress函数的建议。修正了。我只是删除了目录名中的三个delimter和它们之间的空格。您只想保留名称的一部分吗？我想保持所有内容都符合delimeter，因此“Time-2016-03.pdf”成为文件夹名称“Time”。我想在创建的每个文件夹中添加“杂志”。所以文件夹变成了“时代杂志”，里面有文件“Time-2016-03.pdf”，等等。好的，所以我在你建议的正则表达式中添加了一个捕获组：
$OrigFolder = "T:\Magazines"
$NewFolder = "T:\Magazines\_Sorted to Move"

# Orphans folder, where files that return null in the regex match will be moved
# Example: file "- title.pdf"
# will be moved to ".\Sorted\_Orphans" folder

$Orphans = '_Orphans' # Use the underscore to sort the folder to the top of the window
