OK, best to use a different temp filename (leftover from bipinajith's code).

Code:
FROM="please check the error"
TO="please check the the warning"
 
for file in *.txt  # replace the extension as per your requirement.
do
        if grep -q "$FROM" "$file"
        then
                sed "s/$FROM/$TO/g" "$file" > tmp.$$
                touch -r "$file" tmp.$$
                mv tmp.$$ "$file"
        fi
done
