find/xargs question...

[bruce]

hi...

i have what i think is a combination find/xargs question....

i'm trying to search through a dir tree for files matching certain patterns
and i want to rename the files. i'd also like to ignore certain dirs.

ie...

[root at lserver2 wctest]# ls -al
total 24
drwxr-xr-x  5 root root 4096 Dec 27 21:46 .
drwxr-xr-x 48 root root 4096 Dec 27 21:45 ..
drwxr-xr-x  3 root root 4096 Dec 27 21:46 class
drwxr-xr-x  3 root root 4096 Dec 27 21:46 faculty
drwxr-xr-x  7 root root 4096 Dec 27 21:46 .svn

./class:
total 20
drwxr-xr-x 3 root root 4096 Dec 27 21:46 .
drwxr-xr-x 5 root root 4096 Dec 27 21:46 ..
-rw-r--r-- 1 root root  248 Dec 27 21:46 childClass.py
drwxr-xr-x 7 root root 4096 Dec 27 21:46 .svn
-rw-r--r-- 1 root root  239 Dec 27 21:46 zu_fl_2772Class.py  <<<<<

i'd like to find any file with "zu_fl*Class" and replace it with
zu..ClassFFFF. so basically, i'm finding any given file with a pattern
followed by Class, and adding FFFF to it along with the file extension.

i'd also like to ignore specific dirs as well... in this case, i'd like to
ignore the ".svn" folder...

this should be pretty esay, but i can't seem to get the nuances down.

any thoughts/preferrably pointers as to how to perform this action..

thanks
