What is the difference between find with grep?

Question

What is the difference between these command:

find . –type f –name \'*txt*\' 

and

find . –type f | grep \'txt\'

Answer 1

When you have a path with txt in the directory name, the second command will find a match. When you do not want to match paths like txtfiles/allfiles.tgz and transactions/txtelevisions/bigscreen.jpg you will want to use the first.
