man sed

Have you attempted to solve this problem at all? Do you have a script fragment to show us?!

To help you out - (i'd) use sed in a for loop to iterate through the files. But that's all you're getting 'til you post some of your efforts!

You still haven't posted your work so far.

However, benefit of the doubt granted that this isn't some kind of homework problem, then a script such as

#!/bin/sh

for file in /path/to/files/*
do
   sed 's/20040915/20040916/g' $file > $file.new
   rm $file
   mv $file.new $file
done

exit 0

If you want to keep the "old" copies of the files too, just remove the "rm" and "mv" lines from the script.
