This is pretty straightforward. The code assumes that text.txt is in the same directory as your script.
这非常简单。该代码假定text.txt与脚本位于同一目录中。
@echo off
:: Get the first line of text.txt and store the entire thing in a variable
set /p first_line=<text.txt
:: Get an 11-character substring starting at position 25 (substrings start at 0)
set first_line=%first_line:~24,12%
echo %first_line%
