How to Install WP-CLI on Linux.

WP-CLI is a handy tool that greatly simplifies installing and managing WordPress. Its installation requires only a few steps, which we will go through here.

In this tutorial, we assume you are working with Ubuntu and you are logged in as root, so switch to root user if you are not already.

sudo -i

Download and install WP-CLI with following command:

wget https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar \
-O /usr/local/bin/wp \
&& chmod +x /usr/local/bin/wp

Test if the program works.

wp --info

If the WP-CLI is ‘installed’ properly, the output should be similar to this:
