How to use batch processing to realize the central display of text content
This article mainly introduces how to use batch processing to achieve text content center display, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, let the editor take you to understand it.

Code:
[Promise don't come easy]
I should have known all along.
There was something wrong.
I just never read between the lines.
Then I woke up one day and found you on your way.
Leaving nothing but my heart behind.
What can I do to make it up to you.
Promises don't come easy.
But tell me if there's a way to bring you back home to stay.
Well I'd promises anything to you.
I've been walkin' around with my head hanging down.
Wondrin' what I'm gonna do.
'Cause when you walked out that door.
Requirements, the original CMD window, do not adjust the window size, do not generate temporary files, center the display of text content. The output is as follows:

Batman: idea description:
The following code is an example of a full findstr command that uses findstr / n to get line numbers and be compatible with blank lines
And assign the line number as a variable; use findstr / o to get the character offset of the first line, but through the
The character offset between the upper and lower lines is different, because the character offset value is added by class calculation, and each line returns is increased.
Two characters offset, so it is inevitable to impose a carriage return on the last line without destroying the original file
In this case, we have to generate a temporary file; using findstr / o, we can get the character deviation of all lines of the text at one time.
The amount of shift, that is, the total number of characters, must be much higher than judging on a character-by-character basis.

The code is as follows:
@ echo off
