Description of problem:
RHA 030 Chapter 6 Tracking differences diff
Online exercises

My command to answer the question was diff -ru <dir> <dir> >file ( 
the same as an example on the previous page)
The server had the command diff -ur <dir> <dir> >file
 
This command is included in the file and it was this line that was 
being marked wrong even though the rest of the file is the same.

After many attempts occasionally over a few days, and never getting 
the question right, these types of events can very frustrating
