Here is a little script I came across to create a simple html document on the fly;

touch http.sh
vim http.sh

Insert this code into the new script and modify as needed (it can be as simple of as complex as you would like!)

#!/bin/bash
# make_page - A script to produce a basic HTML file

echo ""
echo ""
echo " "
echo ""
echo ""
echo ""
echo " Your page content goes here."
echo ""
echo ""

now save and close the new script. In Vim use

:wq

then

chmod +x http.sh

to make it executable then

./http.sh > mypage.html

to run the script. It will create the file mypage.html. You can modify this script to include any level of complexity you wish.
