推荐答案

.bat文件是DOS遗留下来的. .cmd文件适用于Windows NT命令处理器或更高版本，并且具有更多功能(某些循环结构，能够从过程类型块中调用和返回的功能).

.bat files are left-overs from DOS. .cmd files are for Window NT command processor or higher, and have more capabilities (some looping structures, the ability to call and return from procedural type blocks).

command.com是运行操作系统的系统，包含DOS和早期Windows版本中的内部命令，例如dir. Windows NT引入时，它被cmd.exe取代，并且是第一个32位命令处理器.

command.com was what ran the operating system and contained the internal commands like dir in DOS and early versions of Windows. It was replaced by cmd.exe when Windows NT was introduced, and was the first 32-bit command processor.
