Get-ChildItem 递归但排除父文件夹中的文件

Question

I need to get a list of files in all subdirectories of $PSScriptRoot but exclude any files in the parent folder of $PSScriptRoot.

$Files = Get-ChildItem -LiteralPath $PSScriptRoot -Recurse | Where-Object {!$_.PSIsContainer}

Answer 1

You could list the parent folders first, then recurse each directory for files:

$Files = Get-ChildItem -LiteralPath $PSScriptRoot -Directory | Get-ChildItem -File -Recurse

Answer 2

You can add a Where-Object clause to filter out all files that are directly inside the $PSScriptRoot:

$Files = Get-ChildItem -LiteralPath $PSScriptRoot -Recurse -File | Where-Object { $_.DirectoryName -ne $PSScriptRoot}

^{you can use switch -File instead of Where-Object {.$_.PSIsContainer} as of PowerShell version 3.0}

Answer 3

You just need to call Get-ChildItem again as a pipe

$Files = Get-ChildItem -LiteralPath $PSScriptRoot -Recurse | Where-Object {!$_.PSIsContainer} | Get-ChildItem
