Thanks, this works.

Does this look safe?

find -E $prefix  -regex .*.mp_[0-9]* -exec rm -f {} \;

I'd rather not remove directories so I replace rm -rf with rm -f.

The thing I don't like about this approach is what if I have a  
database named mp_somedb or mp_somedb.mp_sometable in /opt/local/var/ 
db/mysql5/?

To be safer yet is the timestamp always x digits long? I'd rather use  
[0-9]{10}.

I don't really think there is any safe way to do this. I'd like to see  
port keep track of these renames in a registry.

I would really need to move all my data (apache, dovecot, postfix,  
mysql ) outside /opt/local to feel safe with a "find . *.mp* rm"  
approach.
