It should be pretty trivial to do it with sed, awk, or perl. Especially if
you use the same default TTL in all your zones; if you want it to grab the
MinTTL field out of the SOA record and use that, it will take a little more
If you use the same value for all your zones (e.g. 86400 in the example
below), and all your zone file names match db.*, the following should do
for file in db.*; do
echo "$TTL 86400" > $file.new
cat $file >> $file.new
mv $file.new $file
