Every wordpress user loves wordpress’ admin interface. Entire wordpress installation can be managed in one interface. Plugin installation, configuration, updates etc can all be managed from one single interface. What if there is a command line interface for the WP admin functions? That is what exactly provided by WP-CLI. Users with shell skills will love this tool.
WP-CLI is a command line tool for managing wordpress installation. Plugin, Cache, User Capabilities, Comments, Database, Media, Menu, Posts, Theme, Widgets can be managed using this tool. WP-CLI works even in a multi-site WP installation.
WP-CLI comes as a one single binary file which you can save to a location like /usr/local/bin/wp. One installation is enough to manage multiple wordpress installed in a server.
