Geordi is a collection of command line tools we use in our daily work with Ruby, Rails and Linux at makandra.


gem install geordi


The geordi binary holds most of the utility commands. For the few other binaries, see the bottom of this file.

You may abbreviate commands by typing only their first letters, e.g. geordi con will boot a development console, geordi set -t will setup a project and run tests afterwards.

For details on commands, e.g. supported options, you may always run geordi help <command>.

geordi apache-site VIRTUAL_HOST

Enable the given virtual host, disabling all others.

geordi capistrano COMMAND

Run a capistrano command on all deploy targets.

Example: geordi capistrano deploy

geordi clean

Remove unneeded files from the current directory.

geordi commit

Commit using a story title from Pivotal Tracker.

geordi console [TARGET]

Open a Rails console locally or on a Capistrano deploy target.

Open a local Rails console: geordi console

Open a Rails console on staging: geordi console staging

geordi cucumber [FILES and OPTIONS]

Run Cucumber features.

Example: geordi cucumber features/authentication_feature:3

Runs Cucumber as you want: with bundle exec, using parallel tests, with a VNC session holding Selenium test browsers, support for using a dedicated testing firefox and beta support for rerunning failed scenarios.

  • @solo: Generally, features are run in parallel. However, scenarios tagged with @solo are excluded and will be run sequentially, after the parallel run.

  • Debugging: Sometimes, the dot-printing Cucumber formatter does not show errors. In case a feature fails without a message, try running it with --debug or -d.

  • Options: Any unknown option will be passed through to Cucumber, but you need to use an = instead of a space to separate parameter name and value, e.g. --format=pretty.

geordi delete_dumps [DIRECTORY]

Delete database dump files (*.dump).

Example: geordi delete_dumps or geordy delete_dumps ~/tmp/dumps

Recursively search for files ending in *.dump and offer to delete those. When no argument is given, two default directories are searched for dump files: the current working directory and ~/dumps (for dumps created with geordi).

Geordi will ask for confirmation before actually deleting files.

geordi deploy [STAGE]

Guided deployment across branches.

Example: geordi deploy or geordi deploy p[roduction]

Merge, push and deploy with a single command! There are several scenarios where this command comes in handy:

  1. Production deploy: From the master branch, run geordi deploy production. This will merge master to production, push and deploy to production.

  2. Feature branch deploy: From a feature branch, run geordi deploy staging. This will merge the feature branch to master, push and deploy to staging.

  3. Simple deploy: If the source branch matches the target branch, merging will be skipped.

Calling the command without arguments will infer the target stage from the current branch and fall back to master/staging.

Finds available Capistrano stages by their prefix, e.g. geordi deploy p will deploy production, geordi deploy mak will deploy a makandra stage if there is a file config/deploy/makandra.rb.

When your project is running Capistrano 3, deployment will use cap deploy instead of cap deploy:migrations. You can force using deploy by passing the -M option: geordi deploy -M staging.

geordi drop_databases

Delete local MySQL/MariaDB and Postgres databases that are not whitelisted.

Example: geordi drop_databases

Check both MySQL/MariaDB and Postgres on the machine running geordi for databases and offer to delete them. Excluded are databases that are whitelisted. This comes in handy when you're keeping your currently active projects in the whitelist files and perform regular housekeeping with Geordi.

When called with -P or -M options, only handles Postgres resp. MySQL/MariaDB.

When called with --postgres <port or local socket> or --mysql <port or local socket>, will instruct the underlying management commands to use those connection methods instead of the defaults. This is useful when running multiple installations.

Geordi will ask for confirmation before actually dropping databases and will offer to edit the whitelist instead.

geordi dump [TARGET]

Handle dumps (see geordi help dump for details).

When called without arguments, dumps the development database with dumple.

geordi dump

When called with the --load option, sources the specified dump into the development database.

geordi dump -l tmp/staging.dump

When called with a capistrano deploy target (e.g. staging), remotely dumps the specified target's database and downloads it to tmp/.

geordi dump staging

When called with a capistrano deploy target and the --load option, sources the dump into the development database after downloading it.

geordi dump staging -l

geordi firefox COMMAND

Run a command with VNC and test browser set up (alias: chrome).

Example: geordi firefox b cucumber or geordi firefox --setup 24.0

Useful when you need Firefox for Selenium or the VNC set up, but can't use the geordi cucumber command.

Install a special Firefox by calling with --setup <version>.

This command is aliased chrome for users running Selenium in Chrome.

geordi help [COMMAND]

Describe available commands or one specific command.

geordi migrate

Migrate all databases.

Example: geordi migrate

If you are using parallel_tests, this runs migrations in your development environment and rake parallel:prepare afterwards. Otherwise, invokes geordi rake with db:migrate.

geordi png-optimize PATH

Optimize .png files.

Example: geordi png-optimize some/directory

  • Removes color profiles: cHRM, sRGB, gAMA, ICC, etc.
  • Eliminates unused colors and reduces bit-depth (if possible)
  • May reduce PNG file size lossless

geordi rake TASK

Run a rake task in several Rails environments.

Example: geordi rake db:migrate

TASK is run in the following Rails environments (if present):

  • development
  • test
  • cucumber

geordi remove-executable-flags

Remove executable-flags from files that should not be executable.

geordi rspec [FILES]

Run RSpec.

Example: geordi rspec spec/models/user_spec.rb:13

Runs RSpec as you want: with RSpec 1/2 detection, bundle exec, rspec_spinner detection, etc.

geordi security-update [STEP]

Support for performing security updates.

Preparation for security update: geordi security-update

After performing the update: geordi security-update finish

Switches branches, pulls, pushes and deploys as required by our workflow. Tells what it will do before it does it.

geordi server [PORT]

Start a development server.

geordi setup

Setup a project for the first time.

Example: geordi setup

Check out a repository, cd into its directory. Now let setup do the tiring work: run bundle install, create database.yml, create databases, migrate (all if applicable).

After setting up, loads a dump into the development db when called with the --dump option:

geordi setup -d staging

After setting up, runs all tests when called with the --test option:

geordi setup -t

See geordi help setup for details.

geordi shell TARGET

Open a shell on a Capistrano deploy target.

Example: geordi shell production

Lets you select the server to connect to when called with --select-server:

geordi shell production -s

geordi tests

Run all employed tests.

geordi unit

Run Test::Unit.

geordi update

Bring a project up to date.

Example: geordi update

Performs: git pull, bundle install (if necessary) and migrates (if applicable).

After updating, loads a dump into the development db when called with the --dump option:

geordi update -d staging

After updating, runs all tests when called with the --test option:

geordi update -t

See geordi help update for details.

geordi version

Print the current version of geordi.

geordi vnc

Show the hidden VNC window.

Example: geordi vnc or geordi vnc --setup

Launch a VNC session to the hidden screen where geordi cucumber runs Selenium tests.

When called with --setup, will guide through the setup of VNC.


Runs the given command under bundle exec if a Gemfile is present in your working directory. If no Gemfile is present just runs the given command:

b spec spec/models

Stores a timestamped database dump for the given Rails environment in ~/dumps:

dumple development

More information at


Used by the geordi cucumber command. Makes launchy open pages in the user's browser, as opposed to opening it within the VNC window.


Copy lib/geordi/COMMAND_TEMPLATE to lib/geordi/commands/your_command and edit it to do what you need it to do. Usually, it is hard to automatedly test Geordi commands, so make sure you've manually tested it. You can do so by calling your local geordi like so (adjust paths to your needs):

# @option -I: add directory to load path
ruby -I ../geordi/lib ../geordi/bin/geordi <command>

Don't forget to update this README. The whole geordi section is auto-generated by rake readme.

Geordi is (partially) tested with Cucumber and Aruba. Run all tests with rake. Of course you're free to use geordi tests ;)

Note that Geordi still needs to support Ruby 1.8.7, so make sure you only use syntax that was valid back then (e.g. the :old => hash syntax). Unfortunately, it is really hard to get Geordi's tests running on 1.8.7, so you need to make sure it runs on 1.8.7 manually.
