A really basic, hacked together redis cli in ruby. Not even a proper gem or interface, but it's enough to get me by
Make sure you've run bundle install. Then,
REDIS_URI=redis://user:pass@host:port/ bundle exec ruby cli.rb
You will then have a console with the connection defined under REDIS
pry(main)> REDIS.set 'abc', 'def' pry(main)> REDIS.get 'abc' => 'def'
