How to update weather script every hour?

[stu90]

Hello,

i had a go at making a script to download a .txt file for local weather - i have put this in /startup to downloads on each boot, what i would like to do now is have this script automatically run every hour to download an updated weather .txt file.


Here is the script in /startup

Code: Select all

#!/bin/sh


if [ /root/EGXE.TXT ];then 
 rm /root/EGXE.TXT 
fi

wget http://weather.noaa.gov/pub/data/observations/metar/decoded/EGXE.TXT

if [ /root/Startup/EGXE.TXT ];then 
 mv EGXE.TXT /root/EGXE.TXT
fi

For the downloaded .txt file i have made another script that uses xmessage to display the content of the .txt file.

Code: Select all

#!/bin/sh 
            
xmessage -buttons "Exit" -fg "#59FF00" -bg "#000000" -title Weather -center -file /root/EGXE.TXT -timeout 10

I really don't know anything about writing scripts so any help with A. writing them correctly and B. how to run the one in /startup every hour would be much appreciated.

thanks.

cron is the daemon usually used to perform actions on a schedule.

Well I'm a little rusty on my BASH(working on c++ now) but I think the best way would be

Code: Select all

sleep 3600

Now I can't remember wether sleep does miliseconds or not(sleep does in c++) but that should work if it does seconds

or you could always do

Code: Select all

sleep 60m

(I think)

or

Code: Select all

sleep 1h

(again I think I haven't done BASH in months now)


Hope this helps

Hi amigo,
I tried to set up something called crontabs this afternoon but couldn't get it to work - do you have any examples on how i may use cron in my script.

Hi thelaptopkiller,
i tried adding sleep 3600 first at top of script then at bottom but for some reason it only runs the once.

Off topic. Santa has just gone past out side sat in the back of a small pick up with wooden rain dears and fairy lights stuck on the side.

I think you can simplify to this:

Code: Select all

#!/bin/sh

if [ /root/EGXE.TXT ];then
 rm /root/EGXE.TXT
fi

wget http://weather.noaa.gov/pub/data/observations/metar/decoded/EGXE.TXT

xmessage -buttons "Exit" -fg "#59FF00" -bg "#000000" -title Weather -center -file /root/EGXE.TXT -timeout 10

Save it to /usr/local/bin as something like /usr/local/bin/weather. Make sure it is executable (right click > permissions > Yes)

Then use Menu > System > Pschedule to schedule it every hr.

If you want it at startup create a link in /root/Startup

I used sed to remove the extraneous stuff in parenthesis, sent the wget messages to /dev/null, added a check to see if you are in X (and use echo instead of xmessage if not), as well as using the wget text directly via pipes without needing to save/remove it

Code: Select all

#!/bin/sh
show_wx() {
 [ $DISPLAY ] && BEGIN='xmessage -buttons Exit -fg #59FF00 -bg #000000 -title Weather -center' \
 && END='-timeout 10' || BEGIN=echo
 $BEGIN "`wget -O - http://weather.noaa.gov/pub/data/observations/metar/decoded/EGXE.TXT 2>/dev/null \
 |sed 's/([- a-zA-Z0-9]*)//g'`" $END
}

show_wx
while (sleep 3600) do show_wx; done

this is one that you would run as a daemon in the background such as:

show_wx &

(if you wanted to get really creative you can use Xdialog and pick an icon based on the Weather:)

vovchik:
Thanks for script, think i need to install bacon on Lucid puppy for it to work, will look into it.
cheers.


Trapster:
I have been using Puppy pretty much exclusively for a year now and i didn't even know about Pschedule on the plus side it worked a treat and i now get update weather every hour.
thanks.

technosaurus:
Thanks for script, will make a new file and try it tonight.
cheers.

Hi again stu90,

I have a Firefox RSS feed to my BBC weather forecast (see picture for your area), but I tried your method (non-auto just typing weather in the console) and it worked fine.

My regards

Here's the icons that you may want.. Here's a script to show how the icons can be used..

Here's a snippet that shows how Xdialog can be used

Code: Select all

 Xdialog --title "Weather" --ok-label "close" --icon /root/my-documents/weathericons/a.gif --msgbox "`cat /etc/rc.d/PUPSTATE`" 0 0

just type "Xdialog" for a list of options including geometry to control onscreen placement.. there are plenty of examples around to work out screen size so you don't have to hard code to your screen size.

That's assuming you extracted the icons to /root/my-documents and I just picked an example file on my system to show how to extract info from the file.
hth

Cheers

Hello Sir Jasper,

I downloaded the ubuntu version of snownews which is a text based terminal RSS reader - weather from the BBC worked great, feeds from i think omgubuntu not so good.


01micko,

That looks great, with icons as well going to download load and have a play.

cheers.
