For simple scripts shell is pretty good. It's a sane choice if you plan on embedding a Web application on a device, as PHP is a bit of a PIG.

The Apache2 configuration with .htaccess is straight forward:

Options +ExecCGI
AddHandler cgi-script .cgi

However if you are embedding CGI, use a light httpd like nostromo httpd.

The important element with HTML shell CGI scripts in to ensure you have "Content-Type: text/html" in there with a couple of carriage returns.

#!/bin/sh

title="Shell CGI"

cat <<END
Cache-Control: no-cache
Content-Type: text/html

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8" />
        <title>$title</title>
    </head>
<body>
<pre>
END

wget http://webconverger.com/flower100.png &> /dev/stdout || echo "Permission denied"
env

cat <<END
</pre>
</body>
</html>
END

/dev/stderr outputs to /var/log/apache2/error.log so you need redirect wget output to stdout as I do in this case.
