How do I drop a MongoDB database from the command line?
I found this easy to remember:
mongo //to start the mongodb shell
show dbs //to list existing databases
use <dbname> //the <dbname> is the database you'd like to drop
db //should show <dbname> just to be sure I'm working with the right database
db.dropDatabase() //will delete the database & return { "dropped" : "<dbname>", "ok" : 1 }
The best way to do it is from the mongodb console:
> use mydb;
> db.dropDatabase();
Alternatively, you can stop mongod
and delete the data files from your data directory, then restart.
Hint: you can also move the data files to a subfolder, and delete them if you're sure you no longer need them.
Like this:
mongo <dbname> --eval "db.dropDatabase()"
