Something like this:
for file in *.txt
do
cp $file $file.tmp
cat $file.tmp | sed 's/foo/bar/g' > $file
done

You can use
-i to edit the files in place, so there is neither a need for a temporary file nor for a loop.You could also use perl:
perl -pi -e 's/find/replace/g' *.txt

Just bash
for file in *.txt
do
while read -r line
do
case "$line" in
"*pattern*") line="${line//pattern/new}";;
esac
echo "$line"
done <"$file" > t
mv t "$file"
done
