MD和MKDIR批处理命令有什么区别？

两个命令都创建文件夹。mkdir甚至可以创建子文件夹。
这是唯一的区别吗？
为什么有两个命令在做同样的事情？
我该用哪一个？

最佳答案：

只是同一命令的别名。以下是帮助消息：

C:\>md /?
Creates a directory.

MKDIR [drive:]path
MD [drive:]path

和

C:\>mkdir /?
Creates a directory.

MKDIR [drive:]path
MD [drive:]path

If Command Extensions are enabled MKDIR changes as follows:

MKDIR creates any intermediate directories in the path, if needed.
For example, assume \a does not exist then:

    mkdir \a\b\c\d

is the same as:

    mkdir \a
    chdir \a
    mkdir b
    chdir b
    mkdir c
    chdir c
    mkdir d

which is what you would have to type if extensions were disabled.
