Well you always have the option of using good ol' CGI. Use a small
server like thttpd with nginx serving as reverse proxy for that or a
FastCGI wrapper like fcgiwrap and execute the shell command in the CGI
Perhaps there's a smarter way, don't know how it compares to agentzh's
Nginx embedded Lua module suggestion. You have to try it out.
