• 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 ?
• 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?
• 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
