Honestly nicolatiana that would be good! I'm sure that a lot of db are not know

in a two minutes script you can search like this for db
this one give us some db but not a lot
grep -srni '_prop' /etc/e-smith/templates|less
or this one which is much more verbose
grep -srni '${[A-Za-z0-9]\|$[A-Za-z0-9]\|_prop' /etc/e-smith/templates*| grep '}' |less
we look here about $key{propriety} || 'default_value' or ${key}{propriety} || 'default_value'
good hunt
