批处理脚本以在文件夹中查找空文件 [英] Batch script to find an empty file in a folder

问题描述

我需要标识一个文件夹中的零KB文件，并将输出写入文本文件.以下是我使用批处理脚本找到的代码，我想按照以下要求自定义它们.

I have a requirement to identify a zero KB file in a folder and write the output to a text file. Below is the code I found by using batch script and I would like to customize the same as per my below requirement.

@echo off
set out=found.txt
(for /r c:\myfolderfilestosearch %%F in (*.txt) do (if %%~zF LSS 1 echo %%F)) > %out%
pause

我实际上想创建将结果写入到文件，并且前提是上述文件夹仅包含任何0kb文件，但是即使没有0KB文件，我的上述脚本也会为每个实例创建一个txt文件.

I would actually want to create & write the result to file if and only if the above folder has any of the 0kb files only, but my above script creates a txt file for every instance even if there are no 0KB files.

我认为我们可以使用 if 来实现它，但是正如我所说的，我是新手，如果有人使用脚本对其进行了指导，我将不胜感激.

I think we can implement it by using if else but as I said I am new and appreciate if someone guides on it with a script.

P.S.我也可以用powershell编写脚本.谢谢.

P.S. I am fine to have a script written in powershell as well.Thanks.

推荐答案

PowerShell

PowerShell

Get-ChildItem -Path C:\myfolderfilestsearch -Recurse -Force | Where-Object { $_.PSIsContainer -eq $false -and $_.Length -eq 0 } | Select -ExpandProperty FullName | Add-Content -Path found.txt

要为每次运行重新创建输出文件，请执行以下操作:

To recreate the output file for each run:

(Get-ChildItem -Path C:\myfolderfilestsearch -Recurse -Force | Where-Object { $_.PSIsContainer -eq $false -and $_.Length -eq 0 } | Select -ExpandProperty FullName) | Set-Content -Path found.txt
