• I’m Shawn Hooper, a web application developer from Ottawa.

• I’ve been working in WordPress since 2009.

• I love the working from the command prompt, reminds me of my days running a BBS (in the days before the Internet)

Hi!



Command Line?!



• A set of command line tools that allows you to manage WordPress from the command line.

• http://www.wp-cli.org/

What is WP-CLI ?


http://www.wp-cli.org/


• Anyone really, but mostly:

• Developers

• Theme Designers

• Server Administrators

Who is this for?



Don’t Fear The Command Line



• http://www.wp-cli.org/

• Requires PHP 5.3.2 or later

• Requires WordPress 3.5.2 or later

• A “UNIX-like” environment:

• OSX (Macintosh)

• Linux

• Cygwin (Windows)

What do you need?


http://www.wp-cli.org/


• You need to have SSH access to use WP-CLI. Some shared hosting packages do not allow SSH access

• PlanetHoster, SiteGround, Pantheon, BlueHost, GoDaddy, Media Temple, Windows Azure and more now have CLI support.

• VPS services like Digital Ocean and Linode are ideal.

Hosts



• Download it: curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar

• Set permissions: chmod +x wp-cli.phar

• Move it somewhere useful: sudo mv wp-cli.phar /usr/local/bin/wp

Installing WP-CLI



• Does it work? Type: wp
