How can I list all installed plugins/themes/versions from CLI/API?

Question

I would like to generate a simple text report for a Wordpress instance listing:

• Wordpress version
• plugins installed (version and whether enabled)
• themes and child themes installed (version and whether enabled)

I can get this information from the Dashboard, but is there a way to get it programmatically (with WP CLI, WP API or regular command line calls)?

Answer 1

Using WP CLI, you can record Wordpress version using:

wp core version --extra --path="$SITEPATH" > wp-report.txt

and append a list of plugins (with status and version):

wp plugin list --path="$SITEPATH" >> wp-report.txt

and append a list of themes (with status and version) using:

wp theme list --path="$SITEPATH" >> wp-report.txt

Answer 2

WP CLI is probably the best for this:

WordPress Version:

wp core version --path="$SITEPATH" > wp-report.txt

List Plugins:

wp plugin list --path="$SITEPATH" >> wp-report.txt

List Themes:

wp theme list --path="$SITEPATH" >> wp-report.txt

(replacing $SITEPATH with the WordPress installation directory.)
