　　The most perfect code is as follows (from the code of bjsh on floor 23, I only made a few changes):

　　Code 3:
CODE:
--------------------------------------------------------------------------------

@echo off
cd.>output.txt
for /f "delims=" %%i in ('findstr /n .* test.txt') do (
set "var=%%i"
setlocal enabledelayedexpansion
set var=!var:*:=!
(echo.!var!)>>output.txt
endlocal
)
start output.txt


Learned, an error occurred when running, but the output txt is correct!

Wonderful. I want to add something, not sure if it's correct.

`findstr /n .* test.txt` is to find all lines and prefix each line with a line number like "1:".

So in the subsequent loop, there is such a line: `set var=!var:*:=!` to delete a batch of line numbers like "1:".

If there is any incorrect place, please correct it!
