What it does

It uses free Pushbullet service (https://www.pushbullet.com/) to send notifications from bash. I mostly use it for long-running processes, but it could be used in surveillance systems or just anything you want to be informed of immediatly.

This script is just an easy way to send notifications. It also has the feature to wait for another process to finish, even if it's alredy running.

Usage Examples

pushbullet.sh "Hello World"
pushbullet.sh "Text" "Title"
pushbullet.sh "" "" #empty title shows "user@host"

Wait for a Process to end, then notify

I often start a process, without thinking how long it would take. I just hit "make" and wait for it to finish. Some of these turn out to run fairly long, now I can fire up another shell, and register to get notified when the previous startet make finishes.

For this we use a 3rd parameter. You may leave the other two parameters empty, using the defaults.

pushbullet.sh "" "" 3456
pushbullet.sh "" "" make #this uses pidof to find a make process

Installation

replace YOUR_TOKEN from https://www.pushbullet.com/#settings/account - "Access Tokens"

echo 'ACCESS_TOKEN="YOUR_TOKEN"' | sudo tee /etc/pushbullet.conf
cd /usr/bin
sudo wget https://gist.github.com/LaggAt/6125e64fe753fa84f4521475f7de50e3/raw/pushbullet.sh
sudo chmod +x pushbullet.sh

If you know you're starting a long running task, try this:

./rebuild -j4 ; pushbullet.sh "Done. Exited $?"

./rebuild is the long running process, ";" executeds the right hand command always regardless of the previous command failed, then we send "$?" thru pushbullet, which shows the exit code on your phone.
