MongoDb shell scripting

Do you know if it is possible to get a list of databases(like 'show dbs' in console) from javascript. I want to drop all databases from mongo via javascript file (mongo admin.js), but i can't find a way to list all databases...

Thx

I'm trying to prepare simple script but i can't find out how i can change db from script. Here is the sample javascript script. It always fails on command "use". I tried with db.eval and eval but it fails.

print(db.getMongo().getDBNames());
var environments = db.getMongo().getDBNames()
for(var environmentIndex in environments){
    print(environments[environmentIndex])   
    eval("use staging");
    //db.dropDatabase();
}

Use db.adminCommand('listDatabases'). For other commands see http://www.mongodb.org/display/DOCS/List+of+Database+Commands

EDIT:

In util.js use dbname is defined as:

shellHelper.use = function( dbname ){
    db = db.getMongo().getDB( dbname );
    print( "switched to db " + db.getName() );
}
