通过拖放和过滤文件类型处理文件和文件夹
通过拖放和过滤文件类型处理文件和文件夹
提问于 2018-05-07 20:33:41
我正在尝试创建一个批处理脚本，它可以接受以下三种输入中的任何一种：
-drag并删除文件夹
-drag并删除单个文件
-drag并删除多个文件的选择
并对所有与文件类型列表匹配的文件执行cmd命令(用VLC对一些视频进行转码)。我尝试过很多不同的方法，但每一种方法似乎都有这样或那样的缺点。
我可以让脚本检查是否安装了VLC，确定它是否获得了一个文件、文件或文件夹，并在没有过滤扩展名的情况下处理一个单独的文件；它正在处理多个文件，处理一个文件夹，并按扩展名进行筛选，这使我感到震惊：
@echo off

IF exist "C:\Program Files\VideoLAN\VLC\vlc.exe" (

) else (
Goto :Error_VLCNotInstalled
)
Exit /b

REM I really want to filter for six filetypes here (.mp4, .avi, .mov., .wmv,
REM .flv, .gif) and not affect any others. Forfiles looks like it could
REM work, but I can't figure out how to get it to work on my arguments
REM rather than the entire folder of files that match the filter.

Exit /b我想这是一个普遍的问题:是否有一个普遍接受的框架来使批处理脚本句柄智能地拖放执行？

将其保存为cmd文件，并将目录和文件拖放到其中。看看它是怎么工作的。
@setlocal ENABLEEXTENSIONS
@rem @set prompt=$G
@call :ShowTypes %*
@pause
@exit /b
:ShowTypes
@echo Processing:
:_showTypes
@rem If it exists with a slash appended to the end,
@rem it's directory, otherwise a file type.
@if exist "%1\\" (@set _type=directory) else (@call :SetFileType "%1")
@if "%1" neq "" (echo %1 as %_type%) else (exit /b 0)
@shift
@goto :_showTypes
:SetFileType
@rem %~x1 is the extension of the first parameter passed by caller.
@set _type=%~x1
@rem Remove the dot from the extension string.
@set _type=%_type:.=%
@rem Now _type is whatever the extension was.
@exit /b 0移除前面的@符号，以查看该行的运行情况。
