WP CLI script to update active plugins, and commit each update individually. 99% percent stolen from https://markjaquith.wordpress.com/2018/02/12/updating-plugins-using-git-and-wp-cli/, (ever so slightly) adapted to my own personal workflow

updateWordPressPlugins.sh

for plugin in $(wp plugin list --update=available --status=active --field=name);
do
	TITLE=$(wp plugin get $plugin --field=title)
	wp plugin update $plugin &&
	VERSION=$(wp plugin get $plugin --field=version)
	git add -A wp-content/plugins/$plugin &&
	git commit -m "$(printf "update plugin: $TITLE to $VERSION")"
	echo "$TITLE -> $VERSION" >> updated.txt
done;
