  • I have a custmer's Geovision DVR installed on a closed proxi (only logme-in reaches it). I have to check for reliability but logmein hangs and is too slow a process I made the Geovision software send e-mail every minute to the www.spam.la site. All this script does is to retrieve the e-mail header from spam.la ( no login!), filtering sender, stopping at the first occurrence of the word "secs" ( the age of the last e-mail ). The result is the age of the sender's last e-mail, tiny published on top of my screen once a minute. I can refresh www.spam.la via web browser, but have other things to do. I use it inside Kalarm ( kde task schedule ) set to 1 minute repeat. It can be done without kalarm, using Watch outside the script. Try it out now using my account = geo1 ( change sender by geo1 in this script) Needs curl , osd-bin

    curl http://www.spam.la/?f=sender | grep secs| awk '{print; exit}' | osd_cat -i 40 -d 30 -l 2
