I have a dga file (which can be opened and edited in notepad) that is generated by a third party application. I need to edit one line in the file. The file is called:

"%WORKING_DIRECTORY%\%SOURCE_FILENAME%-output.dga"

Here is a portion of the file:

DGAVCIndexFile7

C:\Personal\Videos\87943231_1280x532_23.976.h264
C:\Program Files\DGAVCIndex\

STREAM 0
FO 2
YUVRGB 1
LUMFILT 0 0
CLIP 0 0 0 0
RANGE 0 117586579
AUDIO 
--------Bulk of the file removed here since it takes up a lot of space--------
SIZ 1280 x 532 
FPS 50 / 2
CODED 3339
PLAYBACK 3339

Notice "FPS 50 / 2"? I need to replace that line with "FPS 24000 / 1001". Any help is very much appreciated. Thanks.

Initially I thought I could just use the find command but it adds the following text to the top of the file:


---------- %WORKING_DIRECTORY%\%SOURCE_FILENAME%-output.DGA

find /V "FPS " "%WORKING_DIRECTORY%\%SOURCE_FILENAME%-output.dga" > "%WORKING_DIRECTORY%\%SOURCE_FILENAME%-output.dga0"
echo FPS 24000 / 1001>>"%WORKING_DIRECTORY%\%SOURCE_FILENAME%-output.dga0"
move /Y "%WORKING_DIRECTORY%\%SOURCE_FILENAME%-output.dga0" "%WORKING_DIRECTORY%\%SOURCE_FILENAME%-output.dga"

Thanks for all the help. I just have a couple more questions.

Here is where I stand:

@SET WORKING_DIRECTORY=C:\Personal\Videos

@echo off & setlocal enabledelayedexpansion
set /p    INPUT_VIDEO="Full path to DGA file: "

Move /Y "%INPUT_VIDEO%" "%WORKING_DIRECTORY%\test.txt"

Set "inputFile=%WORKING_DIRECTORY%\test.txt"
Set "outputFile=%inputFile%-TMP.txt"

>"%outputFile%" (
   For /f "delims=" %%* in (
     'find.exe /n /v ""^<"%inputFile%"'
     ) Do (
     Call:GoParse "''%%*"
     (echo\!WriteLine!)
   )   
)

Move /Y "%outputFile%" "%INPUT_VIDEO%"

Del "%inputFile%"

:end   ----------
     
goto:eof
:GoParse lines
(Set /a i = %i% +1)&(Set Line=%1)
(Set Line=!Line:''[%i%]=!)&(Set "WriteLine=")

(Set Line=%Line:FPS 50 / 2=FPS 24000 / 1001%)

(Set WriteLine=%Line:~1,-1%)
goto:eof

Where would I put a PAUSE so not to close the cmd window once complete? Also, is there a way to use variables for the substitution? For example:

(Set Line=%Line:FPS 50 / 2=FPS %NOMINATOR% / %DENOMINATOR%%)

Just run the script from command line, no pause needed. Othervise, here:

Del "%inputFile%"
pause
:end

When you insert a Pause in the batch you still won't be able to see the results on screen because the output is redirected to the file.

To show output on screen and WRITE it to a file the same time you should insert a TEE routine in the batch.
However, it would also be possible to Echo %WriteLine% simply twice - one it will be redirected for APPENDING to the file and one time for showing the results on the screen.

@echo off & setlocal enabledelayedexpansion

Set "inputFile=C:\test\test.txt"
Set "outputFile=%inputFile%-TMP.txt"

Set "NOMINATOR=24000"
Set "DENOMINATOR=1001"

If exist "%outputFile%" del "%outputFile%"
For /f "delims=" %%* in (
   'find.exe /n /v ""^<"%inputFile%"'
   ) Do (
   >>"%outputFile%" Call:GoParse "''%%*"
   (echo\!WriteLine!)
)   

::# replace original file (! remove 'rem' !)
rem Move /Y "%outputFile%" "%inputFile%"

echo\&pause
:end  ----------
     
goto:eof
:GoParse lines
(Set /a i = %i% +1)&(Set Line=%1)
(Set Line=!Line:''[%i%]=!)&(Set "WriteLine=")

:: string substitution (is case-insensitive!)
:: http://www.robvanderwoude.com/ntset.php#StrSubst
(Set Line=!Line:FPS 50 / 2=FPS %NOMINATOR% / %DENOMINATOR%!)

(Set WriteLine=%Line:~1,-1%)
(echo\!WriteLine!)
goto:eof

for text processing, please get a good text processing tool, such as sed or gawk for windows. eg
