New MAMP WordPress Install via Shell

Roll a new WordPress installation for MAMP with this quick shell script (allows custom inputs for directory, database name, and WP version).

Assuming you have MAMP installed in /Applications/MAMP/htdocs:

1. Download the shell script.
2. Run it in Terminal.
3. Answer the prompts.

From my brief write-up:

I decided to combine the most common, repetitive steps of the process into one useful shell script that:

1. Creates a new directory (and lets me name it)
2. Downloads WordPress from GitHub and checks out whatever version I tell it to
3. Creates a new database (and lets me name it) and gives the MySQL user proper permissions
4. Generates my security keys and adds them to wp-config.php
5. Adds my database name, username, and password to wp-config.php
6. Opens up wp-admin/install.php to lets me complete installation

FAQ

Getting fatal: could not create work tree dir... or having other permissions-related issues? Put sudo in front of the path to the script before running it.
