Use 'sed' like this:

sed -e 's/SEARCHFOR/REPLACEWITH/g' infile outfile

You can let infile[s] be produced by 'find .' if you like or have the file
names in a file...

A little sh-programming like this maybe:

$for i in `find . -name "blah?.txt"`; do
>echo sed -e 's/hello/HELLO/g' $i >$i.tmp
>echo mv -f $i.tmp $i
>done

The '>':s are sh's prompt when doing a multiline command. Preceeding each line
'that does something' with echo is useful when trying out the command. Just
remove them when you're confident the script does what it should.
(It might be a good idea to try it in a temporary directory first...)

Cheers,
