[Perl] Script to check stock


Script to check the stock and their graph :D
Uses finance.yahoo.com to get the graphs.

INPUT : stock.conf : contains stock symbol (one per line ) for each company.
You can find the symbols on http://finance.yahoo.com/lookup, if you don't know.

OUTPUT: Generates a html page that contains the information and graph for the given companies in stock.conf.

Requires: lynx
Usages: Put stocks.cgi and stock.conf in your cgi-bin directory. Open in firefox. Refresh to get latest info.
Note: you can also run the script from shell prompt and then redirect the output to a html file , then open this file in firefox :D But you need to run it every time you want the latest info.
# perl stock.cgi > mystocks.html
# firefox mystocks.html

Here are the files:

----- stocks.cgi ---
#!/usr/bin/perl -w
use strict;
use CGI qw(:standard);
