Connect to a specific database by default in mongodb

Question

I am running a mongodb on a linux box. So every time I connect to it from the console (typing mongo) I get something like this:

MongoDB shell ve         


        

Answer 1

Surprised that I don't find a duplicate of this. Okay, now we have content.

From the command line, just do this:

$ mongo myDatabase

This actually is covered in the documentation, albeit down the page somewhat. No direct link but search for and the same example is there.

Of course you could have done:

$ mongo --help
MongoDB shell version: 2.4.9
usage: mongo [options] [db address] [file names (ending in .js)]
db address can be:
    foo                   foo database on local machine
    192.169.0.5/foo       foo database on 192.168.0.5 machine
    192.169.0.5:9999/foo  foo database on 192.168.0.5 machine on port 9999

Which shows the usage along with other options you can pass in.

Another thing, not quite a default connect but a shortcut is you can do this in the .mongorc.js file:

db=db.getSiblingDB("myDatabase")

Which assigns the variable db to that database so now:

db.collection.find()

Is acting on myDatabase.
