Trying out github's gist feature by sharing the small update script I use to maintain my dotfiles across different systems using Dropbox.

update.sh

#!/usr/bin/env zsh

# This configuration file script will create links to the various
# dotfiles and directories in the user's home directory.  This allows
# for the .configuration directory to be "dropped" in and immediately
# setup the shell, keys, editor settings, environment variables, etc.

# Instructions
#
# 1. Setup a link called ".configuration" that points to the dotfiles
#    directory:
#
#    $ ln -s ~/Dropbox/.configuration .configuration
#
#    This allows for storing the dotfiles at a location that synchs
#    files across different computers, like Dropbox.  Otherwise,
#    dropping the dotfiles into a .configuration directory works as
#    well.
#
#    NOTE: .git directory is ignored, so that you can track the changes
#    to your dotfiles (like I do).
#
# 2. Switch to .configuration and run this script.
#
#    $ cd ~/.configuration
#    $ ./update.sh
#
#    This creates symbolic links to all your dotfiles in your home
#    directory.

# List out the dotfiles in the .configuration directory.
ls -A1 -I '.git' ~/.configuration |
# Pull out the file names on separate lines from the output.
  awk '/^\./ { print $0 }' |
# Pass each file name to create a link to the file in .configuration.
  xargs -I {} ln -fs .configuration/{} ~/{}
