WP CLI command to view user activity is now added to Simple History. The current support is pretty basic, but it’s a nice addition anyway I must say.
wp simple-history list command will give you a listing of the latest events. You can also pass arguments
count=20 to show 20 events instead of the default 10. And pass argument
format=json to output the list in JSON format instead of the ASCII table.
Also in this version: theme file edits are logged, with a “quick diff” showing what’s been changed.
