How to add data in text to output using batch bat

This article will explain in detail how to use batch bat to add and output the data in the text. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

For example, the content of a.txt is as follows:

120, 80, 4000, 25.

120, 80, 4000, 10.

120'80 '4000' 50

60, 80, 3000, 12.

60, 80, 3, 000, 6

Can you output 120'80 '4000' 85?

60,80,000,18 to b.txt?

Implementation code

Echo offfor / f "tokens=1-4 delims=*="% I in (s.txt) do (set / a "_% i_%%j_%%k+=%%l") (for / f "tokens=1-3 delims=_"% I in ('set _') do (echo% i*%%j*%%k)) > b.txt

There are examples in the help documentation:

SET P

All will be displayed

A variable that begins with the letter P
