Note: for some reason again. the original text was was wiped out, so am just winging this frame. There is also a step missing, I added.
Step 1: Get the Pics.
# echo $picfn
wget http://radar.weather.gov/ridge/Thumbs/FWS.png -O fws$DAY.png
We will set it to grab a picture once a minute. AT most once a hour is fine unless you know you have inclement weather coming. Set the collection at 1 per minute for our example. That will fill up a hard drive quickly so be careful.
$ chmod +x d.sh
$ crontab -e to add d.sh to your cronfile.
Step 2: Png to TXT Conversion.
for g in fws*.png
img2txt -W 80 -f utf8 img2txt -W 80 -H 25 utf8 $g > $g.txt
$ chmod +x convert.sh
You see the file names to be converted on the screen as they are processed.
Then you should be able to to list the generated text.files.
$ ls fws*.txt
Note: We used img2txt -W 80 -f utf8 img2txt -W 160 -H 60 utf8 $g > $g.txt
Step 3: Showing the Results.
for g in fws*.txt
tput cup 0 0
$ chmod +x show.sh
Watch the show. If there is not much weather change or you have only collected a few frames as we have done here for sake of brevity, you not see the whiz boom you might want to. Definitely try it when a storm is coming your way (if it is safe to do so!!)
