Cut off block based on certain strings in a file

I have a task to cut off the block starting from certain string in the middle of a file and then to save this upper part of the file into a new file.





;---- Some text A
aaaaaaa1111
……..
aaaaaaa2222
;-----Some text B
bbbbbbbbb1111
…………..
bbbbbbbbb2222


Now I am looking for a batch file to cut off the part starting from:



;-----Some text B


So after cut, the new file looks like:



;---- Some text A
aaaaaaa1111
……..
aaaaaaa2222


All the part starting from:



;-----Some text B
bbbbbbbbb1111
…………..
bbbbbbbbb2222


has been cut off.



I tried to use the Function from DOStip then call that function as below:



@ECHO OFF
REM.-- Prepare the Command Processor
SETLOCAL ENABLEEXTENSIONS
SETLOCAL ENABLEDELAYEDEXPANSION
echo.Extracting hello world block into "Load_SDK.M83" file
call:extractFromFile ";---- Some text A" ";---- Some text B">"Load_SDK.M83"
:extractFromFile - extract lines from a file between begin and end mark

SETLOCAL

    Without us having to go off site, can you please provide a genuine example of the file content, what you require as an end result based upon it, the script you've used in your attempts to achieve it, and how that script fails to perform the task it was written to perform.

  • I note that the content of your file does not match the provided code. We need either genuine content with code written for it, or generic content, (which means that solutions may not work with the actual file content), and code written to match. The code you've added as an edit does not represent the task as you've explained it in your question, which seems to require only a single For loop with an If and a GoTo. Please try harder to produce a question which doesn't require a whole lot more questions.

Based on my comment, a one line single For loop with an If and a GoTo seems to perform the task as shown in your question:



@(For /F UseBackQDelims^=^ EOL^= %%A In ("source.txt") Do @If /I Not "%%A"==";-----Some text B" (Set /P "=%%A"<Nul&Echo=) Else GoTo :EOF)>"result.txt"
