Win Bat 批处理带货切片

有的小伙伴需要把我之前一个视频切片的批处理文件变成windows可用的bat文件。文件名字qiepian.bat，代码如下:

```

@echo off

:: Define variable

set SOME_VAR=C:\cygwin\path

:: Remove directory if it exists

if exist "%SOME_VAR%" (

    rd /s /q "%SOME_VAR%"

) else (

    echo "file not found"

)

:: Copy a file

copy /y "C:\some\file" "C:\to\another\file"

:: Check if variable is empty

if "%SOME_VAR%"=="" (

    echo "SOME_VAR is empty"

) else (

    echo "SOME_VAR not empty"

)

:: Define a function

call :my_function

call :my_function "some param"

goto :eof

:my_function

echo hello from my_function: %~1

goto :eof

```

运行也简单，这样就好: qiepian.bat
