Allow configuring multiple ssh deploy keys with git
#!/bin/bash
# Script to use custom ssh keys for various git repositories
# Run without arguments to get usage info.
#
# How it works:
# When used with SSH, git sends the path to the repository in the SSH command.
# @see: https://github.com/git/git/blob/e870325/connect.c#L1268
# We extract this info and search for a key with the name.
# Based on the source, this seems to be used format since v2.0 at least.
# @see: https://github.com/git/git/commit/a2036d7

Powell's 6-Step Plan to NPM Happiness

When things go wrong:

  1. Do what the error says.
  2. rm -rf node_modules && npm install (if in Ember.js - rm -rf bower_components && bower install)
  3. rm -rf node_modules && rm -rf ~/.npm && npm install
  4. Reinstall node and npm.
  5. Format your harddrive.
  6. Buy a new computer.

A script to install git hooks. Run these as the `postinstall` script in package.json. The example here writes a pre-commit hook that runs `npm test`. By having this as a self-contained script and not as a Grunt or Gulp task, Gulp or Grunt can be strict devDependencies.
/* This script operates asynchronously. It can be written synchronously, but
* not a lot is saved once you try-catch everything. Uses the async module.
*
* MIT licence.
*/
var fs = require('fs');
var path = require('path');
var async = require('async');
// Write as many of these as you like.
