Apples and Oranges -which is the best fruit?
I'd argue that for general scripting purposes then Perl is the most
powerful scripting language there is, but if you are designing a large
user application then maybe it isn't appropriate.

Try googling - there is tons of stuff out there.
For many simple purposes your best scripting language is just sh.
As an example I've attached a simple shell script that acts as
a web browser. I call it webserv.sh
Install the shell script in a directory - say /usr/bin
make sure it is executable
chmod 755 /usr/bin/webserv.sh
edit /etc/inetd.conf and add a line like.....
webcache stream tcp nowait root /usr/bin/webserv.sh webserv.sh
then find the process number of your inetd process
ps | grep inetd
333 root 596 S /usr/sbin/inetd
4560 arm 428 S grep inetd
Then send the inetd process a HUP signal make it reread the config file
kill -HUP 333
Then you should have a "webserver" listening on the webcache port (8080)
assuming your ts7200 has the address 192.168.0.50, point a web browser
at
http://192.168.0.50:8080/hello
a simple fixed hello page
http://192.168.0.50:8080/usage
an example of executing commands and use of refresh
http://192.168.0.50:8080/fred
example of a 404 simple page for a non existant page
http://192.168.0.50:8080/jj
an example of a redirect - if you browser has internet access, you'll
end up at my webpage :-)
The script is only 100 odd lines and is very easy to follow and to
customise for your own usage.
Who needs apache :-)
