Bug Splitting a string and putting another string in the middle?

Hello all!

I'm trying to put together a small script that will take in a file name and attach a datestamp to the end of it (but before the file type extension).

To illustrate...

Before:
filename.txt
anotherfilename.txt

After:
filename_20090724.txt
anotherfilename_20090724.txt

Searching around the forums I've found some pieces that I think are parts of the solution:

Code:
 
date +%Y%m%d ---->gets me my datestamp format
expr index string . ------>gets me the character position of '.'

So now my question is how to substring the file name from the beginning to the period and also substring from the period to the end...giving me my two halves of the full name so that I can concatenate my datestamp in between. Any help is very appreciated.

Thanks!
Glen
