Hi there!

The docker cheat sheet has moved to a Github project under https://github.com/wsargent/docker-cheat-sheet.

	MongoDB provides a Javascript shell. But Javascript is no fun without underscore.js

	Turned out its straight forward to use underscore.js while scripting mongodb.

	Here are the steps.

	1) Use underscore to write your db script file (say my_commands.js)

	E.g: _.each(db.dbname.find().toArray(), function(itm) { ... })

	// http://jsfiddle.net/suBPQ/

	$.ajax({
	url: "http://api_test_server.proudlygeek.c9.io/",
	success: function(data) {
	console.log(data);
	}
	});

	-- show running queries (pre 9.2)
	SELECT procpid, age(clock_timestamp(), query_start), usename, current_query
	FROM pg_stat_activity
	WHERE current_query != '<IDLE>' AND current_query NOT ILIKE '%pg_stat_activity%'
	ORDER BY query_start desc;

	-- show running queries (9.2)
	SELECT pid, age(clock_timestamp(), query_start), usename, query
	FROM pg_stat_activity
	WHERE query != '<IDLE>' AND query NOT ILIKE '%pg_stat_activity%'
