Hi guys,


 
I'm having hard timewith diffutils and I need your help. What I've done is:

-I've created a regsnapshot before installing an app (with regedit's export function from the fullregistry)

-After installing theapp I've taken another snapshot from the registry (same way as above)


 
What I would like to dois to put the new information (difference) from the second.reg file to anotherfile with diffutils.


 
So far I've figured thisout to get the cleanest way:


 
diff -n -a before.txtafter.txt >diff.txt


 
I've renamed the two regfile to txt but I doubt this would matter.


 
But my problem when Iopen diff.txt is this:

Issues I got -and Ican't figure out-:

1.)How to get rid ofthe >  characters from the beginning -so diffutil wouldn't evenwrite it to there in the first place-?

2.)I dont want toinclude diffutil difference notes to the file (e.g.: 3424a3425,3429)

3.)Why diffutil addspaces after every damn character? I can't figure out how to get rid of this-so diffutil wouldn't add a space after every character-


 
What I really need is totake the difference, put it in a new file, without changing anything, so I canuse that information later through a reg file (delete, add, whatever)?


 
Waiting for youranswers,

H0PE
