big diff

Nobody's Hero — Tue, 19 Apr 2005 13:35:22 GMT

I have 2 windows registry files that are 5-6 meg each. I want to find the difference between the 2 files and put them to one file. Just show the difference, not the < and the >.

my output looks like this. Do I need to convert the input registry files from DOS to Unix before I run a diff?

I had to convert it from dos to unix.
then I ran a diff. however my diff output file is kind of complex. Is there any way I can get one report that shows what I need to add to file a to make it equal to file b.

How does you window$ registry files look like?? May be you can run strings command on them. And also dos2ux.

in other words, just show me what is not in file "a". Without showing me everything that is not in "a" and everything that is not in "b". Or am I confused?

my output is huge.
looks like:

diff_file1 (1%)

But it will take forever to make file "a" look like file "b".

You should be able to use diff, as diff only uses about 6 times the file size.

Additionally use the -w (ignore whitespace) option:

diff -w file1 file2

If the cr/lf's are causing problems, then use the dos2ux utility someone pointed out.

Also, add the -i (Ignore case) as I see you have an entry that has ADO and ado in a directory path, yet they are the same file path.

diff -w -i file1 file2

Did you export the registry using regedit? If not, the files are binary. I suggest exporting near the level you are trying to diff:

c:\> regedit /E HKEY_LOCAL_MACHINE/Software/Microsoft/Windows hklm.txt

otherwise the files will be huge. Clean the files with:

$ sed "s///g" > hkml2.txt

Here is my problem.

the registry key looks like:

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{1E083962-829F-11D3-AB5D-00C04F9407B9}]
@="MSOLAPClient Class"

when I run my diff on badbox and good box like 'diff -i -w badbox goodbox > diff_file'

and I do a grep -i olap on diff_file, I dont see anything. for some reason, the diff is not seeing any difference in the files regarding 'olap, even though I know they are different. what is stopping 'diff' from seeing the difference?

Re: big diff

Nobody's Hero — Tue, 19 Apr 2005 14:44:25 GMT

is it because the '@olap' entry is on a different line, because it wrapped?
