RSS News Feed for Gnome with Push Notification

Pre Requirements

• Install rsstail package

For Ubuntu:  apt install rsstail

Fedora: dnf install rsstail

• Install curl package

For Ubuntu: apt install curl

Folder Structure 

In this example I am using /opt/rssnewsfeed location



Make a folder inside the "rssnewsfeed" folder base on the feed name.
Ex: aljazeera 

mkdir aljazeera

 Create a file aljazeera.sh file in side the "aljazeerha folder and past the below content.

#!/bin/bash

#eval "export $(pgrep -u $LOGNAME gnome-session | head -n 1 | xargs -I{} cat /proc/{}/environ | egrep -z DBUS_SESSION_BUS_ADDRESS)";
export "DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus"

_dir="$( cd -P "$( dirname "$0" )" && pwd )"
cd $_dir

_feedname="aljazeera"
_url="https://www.aljazeera.com/xml/rss/all.xml"

_status=`/usr/bin/curl -s -o /dev/null -I -w "%{http_code}" "$_url"`

if [ $_status -ne "200" ];
then
        exit 99
fi

/usr/bin/rsstail -1 -u "$_url"  -lp -H -n 1 > ./$_feedname

_TITLE=`cut ./$_feedname -d$'\n' -f2`
_LINK=`cut ./$_feedname -d$'\n' -f3`
_TIME=`cut ./$_feedname -d$'\n' -f4 | cut -d' ' -f6`

if [ ! -f ./lastnewstime ];
then
        touch lastnewstime
        echo "00:00:00" > ./lastnewstime
fi

_LAST_NEWS=`cat ./lastnewstime`


if [ $_TIME != $_LAST_NEWS ];
then
        notify-send -i $_dir/$_feedname.png "$_TITLE" "$_LINK"
        echo $_TIME > ./lastnewstime
fi

exit 0

Configurations

In .sh file we have change few values.

• DBUS_SESSION_BUS_ADDRESS

To get the "DBUS_SESSION_BUS_ADDRESS" value, you have to run below command in terminal.

pgrep -u $LOGNAME gnome-session | head -n 1 | xargs -I{} cat /proc/{}/environ | egrep -z DBUS_SESSION_BUS_ADDRESS

Update the "DBUS_SESSION_BUS_ADDRESS" value in the script.

• Feed Name and Feed URL

Make the .sh file executable.

chmod 755 aljazeera.sh

Type crontab -e in your terminal.
