Subject: How to sort this hash?

Is it possible to sort the jobs hash below based on values such as
command, start_time and stop_time?

Ideally, sort_by would be dynamically provided and I would output the
jobs entries based on the value defined for sort_by.



--------------------------(basic_script.rb)------------------------
sort_by = "start_time"  #<---- I'd like to use something like this to
define which job is listed first

jobs = {
		"2231" => {"command" => "test_a.bash",
				"start_time" => "20051211",
				"stop_time" => "20051222"},
		"1131" => {"command" => "test_b.bash",
				"start_time" => "20051011",
				"stop_time" => "20051122"},
		"231" => {"command" => "test_c.bash",
				"start_time" => "20051215",
				"stop_time" => "20051227"}
	}

jobs.each do |job, attributes|
        puts "------------------"
	puts attributes["command"]
	puts attributes["start_time"]
	puts attributes["stop_time"]
end
--------------------------(/basic_script.rb)------------------------

This is the default output:
 ./basic_script.rb
------------------
test_c.bash
20051215
20051227
------------------
test_b.bash
20051011
20051122
------------------
test_a.bash
20051211
20051222


Id like to have the dynamics of say, ordering these by attribute such
as start_time:

(I wish I could get this)
test_b.bash
20051011
20051122
------------------
test_a.bash
20051211
20051222
------------------
test_c.bash
20051215
20051227


Any suggestions?

thanks in advance.
