How to cut some blocks off the entire file then save into separated file

[goodywp]

I have a task to cut off some blocks of entire file (Load_all.M83) then save it into a separated file (Load_NAR.M83).
Here is the outline of this entire file structure, it is a catalog file

Now I would like to cut off the block all the strings before the below line, in other words, save the string starting from the below lines
;---- NAR signed binaries
and also need to exclude these strings, sometimes it can have more lines in this block
;---- Groupe data files
-eimport
device txt

then save to a separate file as Load_NAR.M83


I also attached these two files as samples

[Ed Dyreen]

cutoff where ? at a specified byte position or based upon the occurrence of a string ?

based upon the occurrence of a string.
cut off all the strings before this line, in other words to save the strings starting from below line

;---- NAR signed binaries
to the end.
but also need to cut off unwanted string (in this block) as
;---- Groupe data files
-eimport

Thanks

[Ed Dyreen]

Code: Select all

@echo off &setlocal enableDelayedExpansion

set "$fileIn=Load_all.M83"
set "$fileOu=Load_NAR.M83"

> "!$fileOu!" type nul

for /F %%? in ( '^( find /V /C"" ^< "!$fileIn!" ^) 2>nul' ) do set "$NumberOfLines=%%?"

< "!$fileIn!" (

	set /A $at = 0 &for /L %%i in ( 1, 1, !$NumberOfLines! ) do (

		set "$=" &set /P "$="
		
		if defined $ if "!$:;---- NAR signed binaries=!" NEQ "!$!" set /A $at = 1
		
		if !$at! NEQ 0 (

			set /A $filter = 0
			
			if defined $ if "!$:;---- Groupe data files=!" NEQ "!$!" set /A $filter = 1
			
			if !$filter! EQU 0 >>"!$fileOu!" (echo(!$!)
		)
	)
)

Just out of my head, this may work.

Hope there are no exclamation marks and carets in that file because I am not protecting any tokens that are problematic.

Thanks! ED! tried and got
2> was unexpected at this time. It was part of code

Code: Select all

for /F %%? in ( '^( find /V /C"" ^< "!$fileIn!" ^) 2>nul' ) do set "$NumberOfLines=%%?"

When I took it off, it works but have some extra lines before the String

Code: Select all

for /F %%? in ( '^( find /V /C"" ^< "!$fileIn!" ^)' ) do set "$NumberOfLines=%%?"

;---- NAR signed binaries

And there are some cut off towards end, meaning less than expected..
Thanks for the effort!

my mistake, 2>nul should be 2^>nul because it's in a for. You need it because otherwise zero length files will be miscounted as length 1 where it should 0. That is find will echo a message on stream 2 also known as stderr, 2>nul means redirect stream 2 to device nul.

And there are some cut off towards end, meaning less than expected..
Thanks for the effort!

if you can't solve it post an example so we can figure out what you expect and what is happening.

Tried as you suggested and similar to my previous trying.
Got some extra line before the start string and end up earlier, meaning cut off some wanted strings. I attached the results of this try

I don't see anything wrong, this is what I get when running your input file from the first post. Starting where you said it should and stripping of the line ';---- Groupe data files'. Or do all consecutive lines after the line ';---- Groupe data files' need to be stripped of also until the next line starting with a ";" ?

I also used this site library function as below:

I tried the above code to see if I can get anything, but not working, any reason about the set variable for bmk and src ???

[Ed Dyreen]

I downloaded your sample, and I notice the file is using LF as line terminator but dos expects CRLF. So the lines are never terminated and cause the variable to overflow as it can only hold 8kb and your input is 12kb which I believe explains the data getting lost. Then this 8kb is treated as a single line because DOS doesn't use LF as terminator.

If I convert the LF terminators to CRLF it seems ok.

I want you to create a file LFtoCRLF.CMD. In there put this

Code: Select all

@echo off &setlocal disableDelayedExpansion &title %~n0

set "$iFile=%~1"
set "$oFile=%~dp0%~nx1"

echo.¯ '%$iFile%'
type "%$iFile%" &echo.
echo.® '%$iFile%'

more "%$iFile%" > "%$oFile%"
echo.

echo.¯ '%$oFile%'
type "%$oFile%" &echo.
echo.® '%$oFile%'

Now backup your original input and drag and drop it onto LFtoCRLF.CMD. Now try this converted file as your input.

Thanks so much ED! I would like to know if there is a better way to do the convert. BTW, I was trying to drag and drop and looks like not working, please a little bit details

I used this piece code to do the convert and works.

set "$iFile=Load_old.M72"
set "$oFile=Load_all.M72"

(for /f ^"usebackqeol^=^

delims^=^" %%? in (

       "%$iFile%"

) do   (echo(%%?)

)> "%$oFile%"

echo.
echo.'%$oFile%'
type "%$oFile%"

pause
exit

and it works pretty well! Thanks again!

I don't see anything wrong, this is what I get when running your input file from the first post. Starting where you said it should and stripping of the line ';---- Groupe data files'. Or do all consecutive lines after the line ';---- Groupe data files' need to be stripped of also until the next line starting with a ";" ?

Is any better way to do it instead of hardcoded

I downloaded your sample, and I notice the file is using LF as line terminator but dos expects CRLF. So the lines are never terminated and cause the variable to overflow as it can only hold 8kb and your input is 12kb which I believe explains the data getting lost. Then this 8kb is treated as a single line because DOS doesn't use LF as terminator.

If I convert the LF terminators to CRLF it seems ok.

I want you to create a file LFtoCRLF.CMD. In there put this

Code: Select all

@echo off &setlocal disableDelayedExpansion &title %~n0

set "$iFile=%~1"
set "$oFile=%~dp0%~nx1"

echo.¯ '%$iFile%'
type "%$iFile%" &echo.
echo.® '%$iFile%'

more "%$iFile%" > "%$oFile%"
echo.

echo.¯ '%$oFile%'
type "%$oFile%" &echo.
echo.® '%$oFile%'

Now backup your original input and drag and drop it onto LFtoCRLF.CMD. Now try this converted file as your input.

Thanks so much ED! I would like to know if there is a better way to do the convert. BTW, I was trying to drag and drop and looks like not working, please a little bit details

The output file will have the same name as the input file and will be placed in the same directory as LFtoCRLF.CMD the input file should be in a different folder or more will be using the same input as output file which doesn't work. If you want the output filename to be different from the input filename so this doesn't happen you can change set "$oFile=%~dp0%~nx1" to set "$oFile=%~dp0_%~nx1" for example.

The conversion is done by this single line more "%$iFile%" > "%$oFile%" and should work.
