MongoDB drop every database

Question

I would like to know if there\'re a command to drop every databases from my MongoDB?

I know if I want to drop only one datatable, I just need to type the name of the dat

Answer 1

Save this to drop_all_dbs.js:

var databases = db.getMongo().getDBNames()
for(var i in databases){
    db = db.getMongo().getDB( databases[i] );
    if(db.getName() == "admin" || db.getName() == "local"){
        print("skipping db " + db.getName())
        continue
    }
    print( "dropping db " + db.getName() );
    db.dropDatabase();
}

Now you can execute:

mongo drop_all_dbs.js

and all databases (except for admin and local) will be dropped.
