How to run a shell script on every request?

[J Carter]

+1 on "why are you doing this?".

However, to answer the question - rather than spawning a new shell for every 
request, use a loop in your bash script that is driven by access log output.

For example.

tail -n0 -f /var/log/nginx/access.log | \
    while read; 
        do echo "one request";
    done;

You'll need to handle what happens when log rotation takes place.
