mongo db quits immediately

Question

Just started working with mongoDB. At first commands received no response, and now it immediately quits. Any ideas of what is going wrong/how I can find out whats going wrong?

Here is the terminal output:

new-host-4:~ Brennan$ mongod
all output going to: /usr/local/var/log/mongodb/mongo.log
new-host-4:~ Brennan$ 

Thanks!

This is the output from the log:

It has started to stay open now but commands don't seem to do anything. Sorry, I cant narrow it down further I am new to mongodb. I'm on a mac using terminal and by typing "help" and then pressing return I should get some sort of response right?

Thanks again!

Figured it out after looking some stuff up on youtube. I was confused as I was coming from a MYSQL background. mongodstarts the server but you need to use mongo to access the shell (I just opened a new terminal wind
