powershell : find subdirectories with the longest paths

Question

我想找到给定目录中子目录中最长的路径，因为我遇到了这个错误:

The specified path, file name, or both are too long.
The fully qualified file name must be less than 260 characters, 
and the directory name must be less than 248 characters.

这是我尝试过的:

$dir = "\\share\server\toto" 
Get-ChildItem -Path $dir -Recurse -Directory | 
Select-Object Name,FullName,
@{Name='FileCount';Expression = {(Get-ChildItem -Path $_.FullName -File -Recurse| Measure-Object).Count}} `
| Format-List *

但这给了我所有目录。

相反，我想找到路径最长的前 5 个目录。

Answer 1

这将返回具有最长路径的 5 个目录:

Get-ChildItem -Path $dir -Recurse -Directory | % { $_.FullName } | Sort-Object { $_.Length } -Descending | Select -first 5
