piping the output of find command to grep
Hi,

I did not understand why the following did not work out as I expected:

find . -name "pqp.txt" | grep -v "Permission"


I thought I would be able to catch whichever paths containing my pqp.txt file without receiving the display of messages such as "find: cannot access... Permisson denied", but it did not work.

Anyone could explain me the reason why ?

Thanks,
Abraham
