Put pushDatabase and pullDatabase in your ~/bin folder. I've removed the extension for easier access.

pullDatabase.rb

#!/usr/bin/env ruby
# encoding: utf-8

require 'rubygems'
require 'net/ssh'
require 'rainbow'

if ARGV[0] && ! ARGV[0].empty?
  name = ARGV[0]
  db_output = %x[ssh {} 'mysql -u{server user} -p{server password} -e "SHOW DATABASES"']
  db_output.each_line do |db|
    if ! db.empty?
      db = db.rstrip
      if db != "information_schema" && db != "Database" && (db.include? name) then
        puts "Found database [#{db}], do you want to continue [N/y]".color(:green)
        response = STDIN.gets
        if response.chomp.strip == "y"
          puts "Pulling database: #{db}".color(:green)
          %x[cd /tmp && ssh {server} 'mysqldump -u{change} -p{change} --add-drop-table #{db} | gzip -v -9' > #{db}.sql.gz && gunzip < #{db}.sql.gz | mysql -u{change} -p{change} #{db}]
        else
          puts "Stop".color(:red)
        end
       break
      end
    end
  end
else
  puts 'You have to provide a project name'.color(:red)
end
