报告无法删除在DEL批处理文件的文件 [英] Reporting failed to delete to a file in DEL batch files

问题描述

怎样才能创建一个报表文件，其中一个DEL命令未能正确执行？

How does one create a report file where a DEL command failed to execute properly?

我还以为你会怎么做：

DEL FILENAME.TXT ECHO "FILENAME.TXT" >> REPORT.TXT

但它的作用是使一个空的报告文件，无论是否发现FILENAME.TXT与否。我想创造一个失败，如果有删除FILENAME.TXT不管什么原因，在弹出的消息被倒入REPORT.TXT的报告文件。

but all it does is make an empty report file, regardless of if it finds FILENAME.TXT or not. I'm wanting to create a report file where if it failed to delete FILENAME.TXT for whatever reason that the message that pops up is dumped into REPORT.TXT.

任何想法？

推荐答案

即使没有找到文件DEL命令总是返回错误code 0，或者如果文件需要管理员权限，所以你需要检查，如果文件仍然存在试图删除后：

The Del command always returns errorcode 0 even if file is not found or if file need admin access, so you need to check if file still exist after trying to delete it:

@Echo OFF

Set "File=File.txt"

Del "%File%" 2>NUL & If exist "%File%" (
    Echo [+] File failed to delete: "%File%" >> "Report.txt" 
)

Pause&Exit

有关的大量文件，你可以做一个程序，不写一个大code，是这样的：

For a large amount of files you can make a procedure to not write a large code, like this:

@Echo OFF

Call :ReportDelete "C:\File1.txt"
Call :ReportDelete "C:\File2.txt"
Call :ReportDelete "C:\File3.txt"
Call :ReportDelete "C:\File4.txt"
Call :ReportDelete "C:\File5.txt"

Pause&Exit

:ReportDelete
(Del "%~1" 2>NUL & If exist "%~1" (Echo [+] File failed to delete: "%~1" >> "Report.txt")) & (Goto:EOF)
