Command line options for ` rails new --help ` (Rails 4.2). Useful for planning new Ruby on Rails app. 'Where can I find options for “rails new” command?'
Because I couldn't find these with a quick Google search on 28 April 2015:
Usage:
rails new APP_PATH [options]
Options:
-r, [--ruby=PATH] # Path to the Ruby binary of your choice
# Default: /home/brian/.rvm/rubies/ruby-2.2.0/bin/ruby
-m, [--template=TEMPLATE] # Path to some application template (can be a filesystem path or URL)
[--skip-gemfile], [--no-skip-gemfile] # Don't create a Gemfile

Ansible: ./configure, make, make install
# This works
- name: Install unixODBC
command: sudo {{ item }} chdir="/tmp/{{ mysql_odbc_unixodbc_url | basename | replace('.tar.gz', '') }}"
with_items:
- ./configure --prefix=/usr/local
- make
- make install
# This _doesn't_ work
# Why doesn't the chdir option get recognized?
# Author: Pieter Noordhuis
# Description: Simple demo to showcase Redis PubSub with EventMachine
#
# Update 7 Oct 2010:
# - This example does *not* appear to work with Chrome >=6.0. Apparently,
# the WebSocket protocol implementation in the cramp gem does not work
# well with Chrome's (newer) WebSocket implementation.
#
# Requirements:
# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby

Big list of http static server one-liners

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
