move-item在循环中不起作用

Question

ls *.gif | Foreach { $newname = $_.Name -replace '\[','' -replace '\]',''
                     write-host $_.Name $newname
                     move-Item -Path $_.Name -Destination $newname; }
ls *.gif

因此,在尝试帮助某人使用[]重命名文件时,我发现move-item在循环中不起作用.它似乎在循环外工作得很好.

想法？

更新:根据下面的评论,我想澄清一下:文件名中的特殊字符要求您使用-LiteralPath参数.-Path无法处理这些字符.在循环之外,-Path有效,因为你使用`来转义特殊字符.在走过一个集合时,这是不可能的.

在循环中,您需要使用-LiteralPath参数而不是-Path.

-LiteralPath <string[]>
    Specifies the path to the current location of the items. Unlike Path, the value of
    LiteralPath is used exactly as it is typed. **No characters are interpreted as 
    wildcards. If the path includes escape characters, enclose it in single quotation 
    marks.** Single quotation marks tell Windows PowerShell not to interpret any 
    characters as escape sequences.

那么,这将是:

GCI -Recurse *.txt | % { Move-Item -LiteralPath $_.FullName -Destination "SomenewName" }
