Adding to @ALoR's answer, for convenience you can put the following in ~/.mongorc.js

function dropDatabases(){
    var mongo = db.getMongo();

    var dbNames = mongo.getDBNames();
    for (var i = 0; i < dbNames.length; i++) {
        var db = mongo.getDB( dbNames[i] );

        print( "Dropping database " + db.getName() + "..." );
        db.dropDatabase();
    }
}

Then at the mongo shell you can simply do

dropDatabases()

From the docs:

Mongo will read the .mongorc.js file from the home directory of the user invoking mongo. In the file, users can define variables, customize the mongo shell prompt, or update information that they would like updated every time they launch a shell.
