我一直在测试一个批处理文件，用来查看我的想法是否可以批量工作。我有一个制作日志系统的想法，但是如果找不到该文件，则不会显示“ 系统找不到指定的文件。”
我尝试过/**
* vmalloc_exec - allocate virtually contiguous, executable memory
* @size: allocation size
*
* Kernel-internal function to allocate enough pages to cover @size
* the page level allocator and map them into contiguous and
* executable kernel virtual space.
*
* For tight control over page level allocator and protection flags
* use __vmalloc() instead.
*
* Return: pointer to the allocated memory or %NULL on error
*/
void *vmalloc_exec(unsigned long size)
{
return __vmalloc_node(size, 1, GFP_KERNEL, PAGE_KERNEL_EXEC,
NUMA_NO_NODE, __builtin_return_address(0));
}
和arc diff，但是第一个刚刚退出了文件，第二个显示了：
arc diff --reviewers 'xxx'
下面是您需要重新创建的所有内容。
type A6Test.log &if %ERRORLEVEL%==1 >nul如果文件不存在，但我希望type A6Test.log ^&if %ERRORLEVEL%==1 >nul不显示任何内容，但显示为：
The system cannot find the file specified. Error occurred while processing: A6Test.log. The system cannot find the file specified. Error occurred while processing: &If. The system cannot find the file specified. Error occurred while processing: 1.
