我试图限制我写的文件夹搜索脚本的递归深度。我试图限制到最多五个级别
基本上我想得到这样的东西:
h:\demo\1st level
h:\demo\1st level\2nd level
h:\demo\1st level\2nd level\3rd level
h:\demo\1st level\2nd level\3rd level\4th level\
h:\demo\1st level\2nd level\3rd level\4th level\5th level
这是我的代码:
function Get-ChildItemRecursive {
[CmdletBinding()]
Param(
[Parameter(Mandatory=$true, ValueFromPipeline=$true,
ValueFromPipelineByPropertyName=$true)]
[string]$FullName,
[Parameter(Mandatory=$false)]
[int]$Depth = 0
)
Process {
if ($Depth -ne 1) {
$newDepth = if ($Depth -gt 1) { $Depth - 1 } else { $Depth }
Get-ChildItem -Path $FullName -Directory |
Get-ChildItemRecursive -Depth $newDepth
}
else {
Get-ChildItem -Path $FullName -Directory
}
Get-ChildItem -Path $FullName -File
}
}
Get-ChildItemRecursive -FullName 'H:\demo\' |
Where {$_.PSIsContainer -eq $True} | select @{Name='Date Modified';
Expression = {$_.LastWriteTime.ToString('MM/dd/yyyy')}},
@{Name='Owner';E=
{(($_.GetAccessControl().Owner.Split('\'))[1])}},
FullName | Export-Csv 'H:\demo\scan1.csv' -NoTypeInformation
我得到的输出:
Get-ChildItemRecursive -FullName 'H:\demo\' |
Where {$_.PSIsContainer -eq $True} | select @{Name='Date Modified';
Expression = {$_.LastWriteTime.ToString('MM/dd/yyyy')}},
@{Name='Owner';E=
{(($_.GetAccessControl().Owner.Split('\'))[1])}},
FullName | Export-Csv 'H:\demo\scan1.csv' -NoTypeInformation
PS H:\> Get-ChildItemRecursive
cmdlet Get-ChildItemRecursive at command pipeline position 1
Supply values for the following parameters:
FullName: H:\demo\
Directory: H:\demo
Mode LastWriteTime Length Name

PS H:\>
您无法在PowerShell v4或更早版本中限制Get-ChildItem -Recurse
的递归深度。相应的参数是added with PowerShell v5:
-深度
在Powershell 5.0中添加的此参数使您可以控制递归的深度。您可以使用-Recurse和-Depth参数来限制递归。
输入:UInt32 参数集:(全部) 别名:
必需:错误 职位:命名 默认值:无 接受管道输入:False 接受通配符:False
并且你的尝试不起作用,因为-Path 'H:\demo\*\*\*\*\*'
从5级深度获取文件夹内容。它不包括该级别以上的内容。
如果无法升级到PowerShell v5,则可以实现一个递归函数,该函数在没有Get-ChildItem
的情况下调用-Recurse
。像这样的东西:
function Get-ChildItemRecursive {
[CmdletBinding()]
Param(
[Parameter(Mandatory=$true, ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true)]
[string]$FullName,
[Parameter(Mandatory=$false)]
[int]$Depth = 0
)
Process {
if ($Depth -ne 1) {
$newDepth = if ($Depth -gt 1) { $Depth - 1 } else { $Depth }
Get-ChildItem -Path $FullName -Directory | Get-ChildItemRecursive -Depth $newDepth
}
Get-ChildItem -Path $FullName
}
}
Get-ChildItemRecursive -FullName 'H:\demo' -Depth 5 |
Where {$_.PSIsContainer -eq $True} |
...
它不是那么美丽,但你可以试试这个:
# First lvl
Get-ChildItem -Recurse -Path 'D:\Test' | Where {$_.PSIsContainer -eq $True} | select @{Name='Date Modified'; Expression={$_.LastWriteTime.ToString('MM/dd/yyyy')}}, @{Name='Owner';E={(($_.GetAccessControl().Owner.Split('\'))[1])}}, @{Name='FullnameLvl0';E={(($_.Fullname.Split('\')[0] + "\" + $_.Fullname.Split('\')[1]))}} | add-content D:\Test\test.csv
# Sec lvl
Get-ChildItem -Recurse -Path 'D:\Test' | Where {$_.PSIsContainer -eq $True} | select @{Name='Date Modified'; Expression={$_.LastWriteTime.ToString('MM/dd/yyyy')}}, @{Name='Owner';E={(($_.GetAccessControl().Owner.Split('\'))[1])}}, @{Name='FullnameLvl1';E={(($_.Fullname.Split('\')[0] + "\" + $_.Fullname.Split('\')[1])+ "\" + $_.Fullname.Split('\')[2])}} | add-content D:\Test\test.csv
#...etc
