searching for a file

[Gill E. Fuchs]

how would one search for a filename in a directory hierarchy?

supose i know there exists a file call  gugu  but i cannot remmember
in which sub-directory?

i was thinking of using :
        find . -name 'gugu' -print
but obviously that only works for the current directory
how would one make that a recursive search, something a la ls -R

still in search of gugu
