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
