2. • 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!

3. Command Line?!

you to manage WordPress from the
command line.

What is WP-CLI ?

5. • Anyone really, but mostly:
• Developers
• Theme Designers
• Server Administrators
Who is this for?

6. Don’t Fear The
Command Line

7. • 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?

8. • 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.
