powershell - 获取名称文件夹的一部分

Question

我使用powershell，我需要获取name文件夹的一部分并将其设置为变量。例如，我有名为“test-123”的文件夹，目录为c：\ tmp \ test-123。

我需要将变量设置为仅仅“-123”并使用它来插入.txt文件（替换其他一些文本）。有什么办法吗？

Answer 1

内置字符串操作非常简单。

$FullFolderPath = 'C:\tmp\test-123';

#Depending on PowerShell version, you may need ToString() here.
$FolderName = (Split-Path $FullFolderPath -Leaf).ToString();

#Gets the index of the first dash in the file name.  If you know you
#need the last dash, use LastIndexOf('-') instead.
$DashIndex = $FolderName.IndexOf('-');

#Return a substring from a starting position to the end of the string
$FolderNameFromDashToEnd = $FolderName.SubString($DashIndex);

$FolderNameFromDashToEnd现在应该具有值-123。

或者也许：

$TestPath = "c:\tmp\test-123";

$TestPath.Split('-') | % { $Wanted = "-" + $_ }

$Wanted
