Full Discussion: Simple directory tree diff script

I suspect that there is simply an issue with the reported size, since all of the file name match. For both partitions, they are windows ntfs, and the copy is smaller the the source. The copy was made using cp -Rfp under cygwin, so it may be that cp stored the copies more efficiently than they were stored in the original versions.

If I was to use the two sorted find files as a starting list for cmp, how would I differentiate the entries in the sorted list that are directories from those that are files? Since cmp is for files, will it just throw an exception if what you pass to it is a directory?

---------- Post updated 03-18-13 at 12:31 AM ---------- Previous update was 03-17-13 at 09:16 PM ----------

I have added the following to the end of my script to check each file pair with cmp. If I get this working, I will add logic to run this part based on an argument.
Code:
# further process sorted find list by checking each file pair with cmp
while read input
do
#  remove leading . from each line in find output
   TEMP=$(echo $input | sed 's/^.//g')
#  escape spaces
   LOCALFILE=$(echo $TEMP | sed 's/ /\\ /g')

   echo $TREE1$LOCALFILE
   echo $TREE2$LOCALFILE

   cmp $TREE1$LOCALFILE  $TREE2$LOCALFILE > $TMPDIR'/byte_compare.txt'

done < $TMPDIR'/check_1_sorted'

This uses one of the sorted find lists to identify each file. If the entry from find is a directory, is seems as if cmp just prints a notification to stderr and moves on. The problem I am having now is that cmp won't except what I have done above to escape the spaces in file names. I have done echo on the path for each file, and it appears correct, but I am getting an error from cmp,

/cygdrive/e/nlite/Presets/Last\ Session_u.ini
/cygdrive/i/nlite/Presets/Last\ Session_u.ini
cmp: invalid --ignore-initial value `/cygdrive/i/nlite/Presets/Last\'

cmp doesn't seem to be seeing anything past the escape. Am I not escaping this properly? If I don't escape the space, I get a similar error indicating that the space is breaking the input.
