Monitoring an html web page changes
Hello,
I need to monitor an html web page for ANY changes and should be able to know if it's modified or not (since last query). I do not need what modifications but just notification is enough.
This is a simple web page and I don't need to parse the links any further.
Is it possible to do it using a shell script, if yes please advise me how to do it.
Thanks!

I got it done by using wget and keep downloading html files and comparing with last previously downloaded file. This way works but I just want to know if there's any better way.
Thanks

tv_grab_na_icons
TV_GRAB_NA_ICONS(1p) User Contributed Perl Documentation TV_GRAB_NA_ICONS(1p)
NAME
tv_grab_na_icons - Grab channel icon images or links from zap2it.com
SYNOPSIS
tv_grab_na_icons [--debug] [--links] [--share dir]
tv_grab_na_icons --help
tv_grab_na_icons --version
DESCRIPTIONS
This script goes to the zap2it web site and downloads icon links or images to the share/icons directory.
It was designed to allow icons to be added by tv_grab_na_dd, but there is no reason it can't be used for other purposes.
To minimize the load on zap2it.com, downloaded icons are recommended. Links are available for those applications that need it.
Also to reduce the load on zap2it.com, this script should be run sparingly. There is really no need to run it frequently, new networks or
icons don't show up that often. To emphasize that point, there is no --configure mode, the questions need to be answered each run.
OPTIONS
--links
Store imge URLs in *.url files instead of downloading images.
--share SHAREDIR
Icons are stored in SHAREDIR/icons. The share directory is set at install time, but there may be times when it needs to be specified.
(for example: no write access to the default share directory)
--debug
Turns on debugging mode. The grabber will be more verbose, and saves some extra debugging data with the icons.
--version
Show the version of the grabber.
--help
Print a help message and exit.
