How to log a Batch file error and success
问题
我有一个简单的程序，根据文件扩展名删除文件，该程序由Windows任务触发。我想创建一个日志文件，如果运行成功，它会显示“成功”，如果失败，它会显示“删除失败”。我不确定如何为此创建日志文件。
@echo off
del "D:\BACnet-CSV\Test csv files\Test1\*.csv"
IF %ERRORLEVEL% NEQ 0 goto ERROR
echo SUCCESSFUL
exit /b 0
:ERROR
echo Delete Failed
exit /b 1
我已经搜索了网络并尝试了几种方法，只是无法正确显示。

I have a simple program which deletes a file based on the extension, which is triggered by a Windows Task. I would like to create a log file which if ran would say successful or if it failed would say Delete Failed. I'm not sure how to create the log file for this.
@echo off
del "D:\BACnet-CSV\Test csv files\Test1\*.csv"
IF %ERRORLEVEL% NEQ 0 goto ERROR
echo SUCCESSFUL
exit /b 0
:ERROR
echo Delete Failed
exit /b 1
Thanks
I've searched the Web and tried several things, just couldn't get it to show correctly.

你可以这样检查文件是否已被删除：
@echo off
set LOFILE=D:\BACnet-CSV\Delete_Log_Files\log.txt
echo %DATE% %TIME% >> %LOGFILE%
if not exist "D:\BACnet-CSV\Test csv files\Test1\*.csv" (
echo NOTHING TO DELETE >> %LOGFILE%
exit /b 0
)
del "D:\BACnet-CSV\Test csv files\Test1\*.csv"
if exist "D:\BACnet-CSV\Test csv files\Test1\*.csv" (
echo FAILED >> %LOGFILE%
exit /b 1
) else (
echo SUCCESSFUL >> %LOGFILE%
exit /b 0
)
DEL不会设置ERRORLEVEL，如果它没有删除文件，因此你需要稍作调整。
如果你想摆脱删除消息，可以使用：
```batch
del "D:\BACnet-CSV\Test csv files\Test1\*.csv" 2>nul
你还需要确保你的日志目录存在，否则你将看不到日志文件。
英文:
You can check if the files have been deleted like so:
@echo off
set LOFILE=D:\BACnet-CSV\Delete_Log_Files\log.txt
echo %DATE% %TIME% >>%LOGFILE%
if not exist "D:\BACnet-CSV\Test csv files\Test1\*.csv" (
echo NOTHING TO DELETE >>%LOGFILE%
exit /b 0
)
del "D:\BACnet-CSV\Test csv files\Test1\*.csv"
if exist "D:\BACnet-CSV\Test csv files\Test1\*.csv" (
echo FAILED >>%LOGFILE%
exit /b 1
) else (
echo SUCCESSFUL >>%LOGFILE%
exit /b 0
)
DEL does not set ERRORLEVEL if it doesn't delete a file, so you have to work around this a little.
If you want to get rid of the deletion message, use
del "D:\BACnet-CSV\Test csv files\Test1\*.csv" 2>nul
You also need to make sure that your log directory exists, or else you won't see the logfile.
