Re: diff tool

[Bob Proulx]

Hello Leila,

You posted a very, very large attachment at 357K.  Please don't send
such large attachments to mailing lists.  Also, as far as I can see
the attachment requires a non-free version of unrar in order to decode
it.  As you know GNU is all about free(dom) software.  Please don't
send files that require non-free programs to view.  Free(dom) software
programs such as gzip, bzip2, lzip or xz are better.

I am not sure what you are asking.  I think you have two files that
you think should be different but that the program does not show them
to be different.  Is that correct?

GNU diff is a good tool to display differences in files.

In order to help it is important to know the version of the diff
program that you were using and the operating system upon which you
were running.  You can get the version of diff with the --version
option.

  diff --version

What operating system are you running?

In the future please compress any large attachments.  Use a free(dom)
software compression program such as gzip, bzip2, lzip or xz.  Text
files usually compress very well.

If you think you have a bug in a program try to reduce the size of the
recreation set to the smallest file needed to recreate the problem.
