Code:
ffind . -name Makefile -type f -print -exec tee -a testPaths.log \; | echo -n "."

It just writes a dot to stdout and done. Maybe tee has no input.

Perhaps it just runs too quickly for you to see.
I have tested it on a large folder set. I think that data is collected till end of find, then it is pushed to pipe on by one. In case of "| while" I see that the full time of search elapses and then everything is printed out in a sec.

I would really like to help more but for some reason my ubuntu-terminal rejects the command because "-exec needs arguments" :s
For the meantime:
I don't know if this will work but it's worth trying:
Code:
find . -name Makefile -type f -print -exec > testPaths.log | echo -n "."

I think " \;" is missing from end of -exec

Smilie thanks ^^

maybe the fact that you can use multiple -exec commands for find can help you?
I don't have the time to try it right now sorry (a friend told me) ^^'

Another approach where we can do whatever we like each time we find a file.
Also improved order of parameters on the "find" line which should speed it up.

Code:
>testPaths.log
echo -n "Searching "
#
find . -type f -name Makefile -print|while read filename
do
        # Output filename to file
        echo "${filename}" >> testPaths.log
        # Output dot to screen with no linefeed
        echo -n "."
done
# Output a linefeed 
echo ""
echo "Finished"

Correct me if I am not right, but it seems that "whatever we like" is executed for each file just after find is finished its job in case of

Code:
find . -type f -name Makefile -print | while read filename
do
   ...
done

The construct is dynamic. The find command passes each matching filename to the while loop as it finds it. The while loop ends when find ends.

It is one of the best ways to process open-ended lists in Shell and has the advantage of preserving spaces in filenames.

Though not relevant to your post if you want to find just one file you can exit the loop as soon as you find the file.
