	# install all active plugins basd on the `active_plugins` option value
	wp option get active_plugins --format=json | php -r "foreach( json_decode( fgets(STDIN) ) as \$value ) { \$p=explode('/',\$value);fwrite(STDOUT, (is_array( \$p ) ? \$p[0] : \$p).PHP_EOL); }" | xargs -n1 bash -c '
	VERSION=$(wp plugin get $0 --field=version --quiet)
	echo "Trying to install ${0}"
	if [ ${#VERSION} -gt 0 ]
	then
		echo "Specifying version ${VERSION}"
		wp plugin install $0 --version=${VERSION}
	else
		echo "No version number found"
		wp plugin install $0
	fi'

Only works for plugins on wordpress.org and plugins for which we have .zip download links, so "download" is still kinda better. What if we check for a local version or get a better command than scp in the download?
