SCHEMA="newschema"
function listFiles {
    grep -lRi OLDSCHEMA \
       /dir1 \
       /dir2
}

listFiles | while IFS= read -r file
do
    echo "Replacing OLDSCHEMA with ${SCHEMA^^} in ${file}"
    # ^ upercases the first letter, ^^ upper cases them app
    sed-i "s/CORPDBA/${SCHEMA^^}/g" "${file}"
done
