I think I can do this myself now, but I am always amazed by how people can do things cleaner and simpler than I end up doing...
Using cron, I want to save the image found at:
http://radar.weather.gov/ridge/Conus...ntgrtlakes.gif
every 15 minutes to a local file , such as
/home/bruce/radarpics/2008-06-14_23:15.gif
Some Nuggets I've found so far:
#!/bin/sh -xv
# TEST - Assign Date Value to Variable
d='date +%y%m%d%H%M%S'
echo $d
file="file_$d"
echo $file
The format I would want is:
date -d "-10 seconds" "+%H:%M:%S"
So, what do you think is the BEST way to do this??
(I just discovered this board, but very impressed by the traffic and knowledge I've seen so far!)
