So allow me to play devil's advocate here. SSI (server side includes) is not really what Joe was asking about, his question was closer to using bash cgi. While actually writing something in bash might be a royal pita, I would argue it's not inherently problematic especially if you already have some working code. I think the problem stems from the face that not enough people really understand modern web servers. Web servers only display static assets to clients (generally browsers), that means if you're using a LAMP set up a PHP vm running in mod-php actually runs the PHP code and then apache serves up the static content to the client.
A more common architecture has become nginx -> app server -> database where the app server is frequently php-fpm for php or unicorn for ruby. If you really want to use bash you can google 'bash cgi' and find plenty of examples then just use bash for your app server. This is not necessarily less stable or secure than writing code in php/ruby/perl/ect. That being said bash would not be a friendly language choice for writing a web app in and all the major players allow you to shell out to run commands, so you're likely better off letting a more established stack/framework handle some details and shelling out to any bash code you have written.

This is *not* a good idea. Creating dynamic web pages with shell can be done,
but it's not one of the things that shell is designed for/good at. One way is
briefly described at
http://httpd.apache.org/docs/2.2/howto/ssi.html . You
will have an easier time of it if you use something that's designed for
creating dynamic web pages, like mod_python or CGI-Perl or Ruby on Rails or
PHP.

How is this working? If I paste the above into temp.sh and execute it, it
says "/bin/bash: - : invalid option". If I fix the interpreter line so it
says "#!/bin/bash" , it complains that readin and cls are not valid bash
commands. If I replace "ans=`readin`" with "read ans" and "cls" with "clear",
it fails with a syntax error because "esac done" is in there twice.
