Apche rewrite rule convert to nginx

Hello,
please help me converte apache rewrite rule to nginx:

RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^naujienos+ news.php/$1 [L]
RewriteRule ^naujienos/p(.*)$ /news.php?pg=$1 [nc]
RewriteRule ^naujienos/?$ /news.php [nc]
RewriteRule ^naujienos?$ /news.php [nc]

 

Have you tried these two .htaccess converters?

yes but does not work

 

Try

Code:

if (!-e $request_filename){ 
  rewrite ^/naujienos+ /news.php/$1 break; 
}
rewrite ^/naujienos/p(.*)$ /news.php?pg=$1; 
rewrite ^/naujienos/?$ /news.php; 
rewrite ^/naujienos?$ /news.php;
