It's very easy. Just change "echo variable" to "echo to the file".

Generally speaking, there are mainly 2 key points worthy of learning
1. The usage of "tokens=1 delims=", this point is very easy to get wrong many times
2. Variable replacement and extraction
If the content of ab.txt is changed from the original:
Name "Zhang San", ID '102', tel '0102211', 0, 25, 11
Name "Li Sida", ID '102', tel '0202211', 0, 25, 11
Name "Wang Er", ID '102', tel '01023311', 0, 25, 11
........
To the following:
abcd rster_www_er Name "Zhang San", ID '102', tel '0102211', 0, 25, 11
abcd rster_www_er Name "Li Sida", ID '102', tel '0202211', 0, 25, 11
abcd rster_www_er Name "Wang Er", ID '102', tel '01023311', 0, 25, 11
....
Then the above reference answer codes all need to be appropriately modified.
From this, it can be known that if you are editing a highly universal code, it is best to use the method of fuzzy search and positioning. For example, in this case, even if the length of each line of the ab.txt file and other contents change, as long as there is a field like , it can be found and replaced.
Can this be achieved?

I don't quite understand what you mean.
The idea is to replace "姓名" in each line of the string with "abcd rster_www_er 姓 名", right?
Hahaha

Is that okay?
Haha
No, what I mean is that as a highly versatile search statement, using fuzzy positioning to find is more practical than using the method of finding according to the delimiter.
For example, the content in the original ab.txt file:
Name "Zhang San", ID '102', tel '0102211', 0, 25, 11
Name "Li Sida", ID '102', tel '0202211', 0, 25, 11
Name "Wang Er", ID '102', tel '01023311', 0, 25, 11
This is very neat.
If it is not neat, it becomes:
abcd rster_www_er 姓 名 "Zhang San", ID '102', tel '0102211', 0, 25, 11
abcd, er 姓 名 "Li Sida", ID '102', tel '0202211', 0, 25, 11
abcd rster, www, r 姓 名 "Wang Er", ID '102', tel '01023311', 0, 25, 11
With such a format, the design idea of strictly finding according to the delimiter is almost unusable, and only fuzzy finding can be implemented.
In general, no matter how each line of text becomes, can be replaced in any different position in each line.

Oh, just use the name as the delimiter, right? Write the names after delims=, like 姓 名, 姓 名... and you can get the following names.

Write the name after delims=, such as 姓 名, 姓 名..., and you can get the subsequent names.
Thank you for your answer. After repeated testing and appropriate adjustments, it works.
Your code has very good applicability. Thanks again!

for /f "tokens=1* delims=," %%i in (ab.txt) do (
set data=%%i%%j
set /a mn+=1
for /f "tokens=1* delims=:" %%a in ('findstr /n .* cd.txt') do (
if !mn! EQU %%a set data=!data:%%i=姓名"%%b＂,!
)
echo !data!>>c12.txt
)
pause

Among all the previous responses, terse's one has the strongest adaptability and can be fully adapted to the search and replacement of general-purpose files without modification. Only the "name" field needs to be replaced with what you want to search for.
Thank you, terse

If we extend the problem, for example, the ab.txt file has only this line:
Name "Zhang San", ID '102', tel '0102211', 0, 25, 11
Now the cd.txt file remains unchanged:
Zhao Kuo
Wang Bin
Li Ling
......
Can we replace the name after the first line in the ab.txt file and then directly copy this format to generate a file ef.txt that has exactly the same number of lines as the cd.txt file:
Name "Zhao Kuo", ID '102', tel '0102211', 0, 25, 11
Name "Wang Bin", ID '102', tel '0102211', 0, 25, 11
Name "Li Ling", ID '102', tel '0102211', 0, 25, 11
........
Here the problem is not just about replacing corresponding lines, but also involves copying, which I think will be more complicated.

Hehe, thank you all for your answers. Different program expressions achieve the same goal, which is worth studying carefully.
