Usage: rails COMMAND [ARGS]
The most common rails commands are:
generate Generate new code (short-cut alias: "g")
console Start the Rails console (short-cut alias: "c")
server Start the Rails server (short-cut alias: "s")
dbconsole Start a console for the database specified in config/database.yml
(short-cut alias: "db")
new Create a new Rails application. "rails new my_app" creates a
new application called MyApp in "./my_app"
In addition to those, there are:
application Generate the Rails application code
destroy Undo code generated with "generate"
benchmarker See how fast a piece of code runs
profiler Get profile information from a piece of code
plugin Install a plugin
runner Run a piece of code in the application environment
All commands can be run with -h for more information.
