Cmd command syntax bug

Author: sixth element
Cmd is one of our most commonly used tools. I won't talk about command usage. Everyone on Earth knows it.
The following is a usage that I have discovered without any technical skills. It is just for you to play when you are bored.
For example, if we want to return to the root directory under c: 123, We need to input cd.
You can also type cd = OR = cd,
The upper-level directory cd... can also be returned ..

Create directory command md. If we want to create a qq folder, md qq,
But you can also, = md qq, = qq ==========, md = qq, md ================== qq, haha whatever you call = no one cares about you.

We use cmd to create a folder, as shown in the following figure. it will be ignored by windows. Do not believe it, such as md 123 ., go to the hard disk and check if there is no such point. Even if you add 100 points, it will be ignored, md 123 ...................................... ........................ Haha,
I really don't know what MS engineers are doing.
You can also play md qq, md ,. qq .,, md = ,. qq ., =, md ,. qq ,., processing will be prompted later on this screen. but a folder named qq has been created.

That's all. Let's explore the rest.
Don't forget to let us make progress together. MYQQ: 5876006 sixth element
