Dr. Harrington's Page for Unix Lab CGI Development

Make sure you have an account on a server and can use a terminal interface, as discussed in Linux Basics.
Static web page editing and forms are discussed in Html Form Editing, which suggests starting new forms from formTemplate.html.
See The Overall CGI Process for an introduction to dynamic web pages.

The rest of the page gives links and brief descriptions for all the related pages discussed in links her, plus a few more.

Example pages and scripts:

hellotxt.cgi (source): The simplest noninteractive cgi script, producing pain text output
hellohtml.cgi (source): A slight elaboration, producing html.
now.cgi (source) Reads and displays system clock time

adder.html which uses adder.cgi (source) which plugs into the template adderAnswer.html (Note the %% in adderAnswer.html, because it used as a format string.)
namelist.html: uses namelist.cgi (source) - maintains data in a file and displays a variable number of lines.

file.html: Allows you to see the source code for any readable file on this web site
index.cgi (source): A real application used to speed up display of server directories without index html files. (This uses several library modules we have not discussed - you are not responsible for it!)
dumpcgi.cgi (source) to dump the name and value attributes for any form
