UNIX for Dummies Questions & Answers

I have a folder called {homedata}
Within this folder there are 12 subfolders 200601.......200612
Within each subfolder there are 8 sets of files
Each filename commences with A B C D E F G or H,
so {filename}* can be used.

I am trying to write a script which will from the top level
go through each subfolder and manipulate the files by
copying them to a different location{destinationdata/2006nn/filename}
& then renaming them, by appending _OK to their filename.

Can anybody help please ?

Many thanks
