For multiple files I prefer to do two steps. Do a replace and write the file
to a  temporary file. Once I have reviewed the changes and know that I
haven't done anything horrible. I move them back into place.

 for i in *.TXT; do sed 's/testing/test/g' $i> `basename $i`.TMP; done

review all *.TMP files
and if ok

for i in *.TMP; do mv $i `basename $i .TMP`; done

Thanks
