Original title: txt text content processing problem
Modified title: How to overwrite the content of a specified paragraph in a text with other text content
Description: Because the original title was too vague, it was not convenient for forum search and management. Three days after this notice was posted,
　　the original poster had not changed the title, so I forcibly changed the title and deducted 2 points from the original poster.
────────────────　Moderation Record　────────────────


There are two files, a.txt and b.txt (the content is purely fictional, but it is enough to express my meaning):
The content of a.txt is as follows:
:
monday
:
yang li
wang yu
shan liang
:
meeting
study

The content of b.txt is as follows:
zhou zhuo
tian li
shang xiao nan
sun chao

Can a bat be used to achieve the following function:
Each time first delete all the names after : in a.txt, and then add the name content in b.txt to it, so that it becomes as follows:
a.txt:
:
monday
:
zhou zhuo
tian li
shang xiao nan
sun chao
:
meeting
study

The content in b may always change in the future, I just want to execute the bat, and import them all after name in a.txt.
If the bat cannot achieve this operation, can you tell me how to write it in vbs?
In addition, there is another question, how to start and execute a vbs in a batch file?

Looking forward to everyone's answers, thanks in advance!!!!!!!!!!!!!!!!!!!!!

sed -e "/\:/,/\:/{/^ */d}" -e "/\:/rb.txt" a.txt

Try this command, it's a bit long written in one line.

sed -e "/\:/,/\:/{/^ */d}" -e "/\:/rb.txt" a.txt

Sed download address: http://www.student.northpark.edu/pemente/sed/gsed407x.zip

The meaning of "sed: -e expression #1, char 2: Unterminated address regex" is: In the sed command, in the first expression, at the 2nd character position, there is an unclosed address regular expression.

　　This is an error message from the sed command. It's a syntax error, right?

The function of the SED command is quite good

I got it by typing SED/?

Re qwe1234567
This is an error message. Dude, try with a higher version and download the link on the second floor.

To view the help, you need to type like this: "sed -h"

A while ago there were several posts, but I didn't see your previous replies. Oh my, I thought it was an error message from running the old version. But indeed, there is a problem with the old version sed 302, and a small change is needed.

sed -e "/\:/,/\:/{/^ */d;}" -e "/\:/rb.txt" a.txt

This is too powerful, admire it～:)

@echo off
cd.>test.txt
for /f "tokens=1* delims=:" %%i in ('findstr /n . a.txt') do (
    if not "%%j"==":" (>>test.txt echo %%j) else (
        set line=%%i&goto insert
    )
)

:insert
>>test.txt echo :
>>test.txt type b.txt
>>test.txt echo.

set flag=1
for /f "skip=%line% delims=" %%i in (a.txt) do (
    if "%%i"==":" set flag=
    if not defined flag >>test.txt echo %%i
    
    )
)
start test.txt

If you have to use batch processing to solve it, you can try the following code (if the number of lines in a.txt is extremely large, the speed will be relatively slow):

@echo off
cd.>test.txt
for /f "tokens=1* delims=:" %%i in ('findstr /n . a.txt') do (
    if not "%%j"==":" (>>test.txt echo %%j) else (
        set line=%%i&goto insert
    )
)

:insert
>>test.txt echo :
>>test.txt type b.txt
>>test.txt echo.

set flag=1
for /f "skip=%line% delims=" %%i in (a.txt) do (
    if "%%i"==":" set flag=
    if not defined flag >>test.txt echo %%i
    
    )
)
start test.txt
