Why | doesn't work with find?

Question

Why does the following command aiming to remove recursively all .svn folders

   find . -name ".svn" | rm -rfv

doesn't work ?

I know the find command provides the -exec option to solve this issue but I just want to understand what is happening there.

Answer 1

In your example, the results from find are passed to rm's STDIN. rm doesn't expect its arguments in STDIN, though.

Here is an example how input redirecting works.
