Quick and dirty bash script for quick Laravel 4 install and update. Make sure you already have Composer and git ssh keys working. Both of these files go in /usr/local/bin

laravel4-install

#!/bin/bash
message_prompt="Laravel 4 will be installed in the current directory.\nContinue?"
message_confirm="\nHere we go!"
message_deny="\nJust let me know when you're ready."
echo -e $message_prompt
read -p "" -n 1
if [[ ! $REPLY =~ ^[Yy]$ ]]
then
  echo -e $message_deny
  exit 1
fi
echo -e $message_confirm
git clone [email protected]:laravel/laravel -b develop .
composer install

laravel4-update

#!/bin/bash
message_prompt="Laravel 4 will update the current directory:"
message2_prompt="\nMake sure you are your root application folder.\nContinue?"
message_confirm="\nHere we go!"
message_deny="\nJust let me know when you're ready."
echo -e $message_prompt $PWD $message2_prompt
read -p "" -n 1
if [[ ! $REPLY =~ ^[Yy]$ ]]
then
  echo -e $message_deny
  exit 1
fi
echo -e $message_confirm
composer update
git pull origin develop

Make it check for the composer or composer.phar command as well, and download it if it's not installed.
