New versions of Wordpress are released regularly, and themes and plugins are
upgraded frequently. I wrote
wordpress-install
to make updating a single plugin/theme/Wordpress easy, but it still requires
running a command like wordpress-install DIRECTORY theme twentynineteen for
each plugin/theme/Wordpress that needs to be updated. That’s quite toilsome so I
wrote a simple wrapper around wordpress-install:
update-wordpress-core-plugins-and-themes.
It tries to update every plugin/theme/Wordpress (unless the plugin or theme
contains a file named excluded-from-automatic-updates), so updating everything
is just update-wordpress-core-plugins-and-themes DIRECTORY. The only extra
action needed is when there’s a major update to Wordpress: you need to login as
an admin and go to the updates page to update the database schema.
