Either use the mongo
command line or RoboMongo or MongoChef. Don’t forget that you don’t necessarily have to open 27017
on the network to use it (ssh tunnel & use localhost:27017).
See what databases are available and choose one,
mongo show databases use <database name>
Search for a document containing foo
in the users
collection,
db.users.find({username: 'foo'});
and // makes it case-insensitive,
db.users.find({username: /foo/});
Reset the value for e.g. happyTimeout
in the users
collection on all the documents (multi true),
db.users.update({}, {$set: {happyTimeout : null}}, {multi : true})
Check the db names,
mongo show dbs
Copy & nuke a DB entirely,
db.copyDatabase('dbname', 'dbcopy'); use dbname db db.dropDatabase();
or as one-liner from the shell,
mongo dbname --eval "db.dropDatabase();"
