Documentation page has an example of using --database option

mongooplog  --from mongodb0.example.net --host mongodb1.example.net --database people --collection usage

Stating

In the next command, the parameters limit this operation to only apply operations to the database people in the collection usage on the target host (i.e. mongodb1.example.net):

But the option does not work - I guess "-database" has been renamed to "-db":

$ mongooplog --from 127.0.0.1:20000 --port 20010 --database d01
ERROR: unknown option database

Unfortunately when db is used the mongooplog does not act as described - it applies changes to all database - not only the one specified:

Add doc to replica set "rs0" database "d02"

rs0:PRIMARY> use d02
switched to db d02
rs0:PRIMARY> db.data.save({a:"02"})

Apply oplog from rs0 to rs1 limiting to database 'd01' - change in d02 should not be replicated

mongooplog --from 127.0.0.1:20000 --port 20010 -d d01

but it appears on rs1 after that.

rs1:PRIMARY> use d02
switched to db d02
rs1:PRIMARY> db.data.find()
{ "_id" : ObjectId("5182929363576b32f0144132"), "a" : "02" }
