Is it possible to export WordPress from command line?

export

wp export --dir=/var/www/site.com/htdocs/backup --user=admin --post_type=post --start_date=2021-05-07 --end_date=2021-05-08 --allow-root

import

wp import example.wordpress.2021-05-08.000.xml --authors=create --allow-root

If you are not root, discard --allow-root

Change example.wordpress.2021-05-08.000.xml to your filename

You need to change the information according to your usage. Directory name, filename, etc.

Check out http://wp-cli.org/. It's fantastic and I've used the export capability multiple times.

More information on wp-cli.

WP-CLI is a set of command-line tools for managing WordPress installations. You can update plugins, set up multisite installs and much more, without using a web browser.

You will most likely have to install wp-cli. You can find instructions on wp-cli.org. There are also alternative installation instructions here: https://github.com/wp-cli/wp-cli/wiki/Alternative-Install-Methods

To export your posts using wp-cli, you can use the command.

wp export

There are many options to limit the export by date, post type, category, author, etc. Most details can be found on this page: http://wp-cli.org/commands/export/

I don't know of any other way to export an xml file from the command line.
