File Monitor -> Email

[binaryechoes]

Dilemma:
I need to receive notification via email when updates occur in regards to ISS sensors.

They are posted here.

http://www.iss.net/db_data/xpu/RSNS.php

I'm using wget to retrieve the file for local analysis.
wget -E -N -k

http://www.iss.net/db_data/xpu/RSNS.php

I experimented with

http://www.willingminds.com/resources/filewatcher.html

and can't seem to get the Perl module (Mail::Internet) to forward me the results.

Suggestions?:

If further clarification is needed please respond accordingly.
BTW. Linux compatible...however win32 methods are welcomed.

Thanks,

I'm not at all clear what you are wanting to achieve but it seems as if you are trying to monitor a web page for changes and send yourself email if you find any.

If I'm right, I'd be tempted to [heresy]use a shell script rather than perl[/heresy]. You could certainly do this in perl but it would be quicker to knock up something like

#!/usr/bin/[red]sh[/red]

SAVE=/var/spool/monitor   # our copy of the last version of the page
TEMP=/tmp/monitor.$$      # local copy of the current version
MAIL=me@mydomain.net      # address to notify of changes
PAGE=[URL unfurl="true"]http://www.iss.net/db_data/xpu/RSNS.php[/URL]

wget -O $TEMP $PAGE

LAST=`sum $SAVE`
THIS=`sum $TEMP`

if [ "$LAST" != "$THIS" ] ; then
  diff $SAVE $TEMP | mail -s 'Page has changed' $MAIL
fi

rm $SAVE
mv $TEMP $SAVE

Does that get you anywhere near?

Yours,
