Bash function to update my given IP via Pushbullet

pushbullet IP

#!/bin/bash

function pb_msg {
        curl -vs -o /dev/null \
        -u PUSHBULLET_TOKEN \
        https://api.pushbullet.com/v2/pushes \
        -d type=note \
        -d title="$1" \
        -d body="$2" 2> /dev/null
}

curl http://ipecho.net/plain -o ~/.plain
NEW_IP=`cat ~/.plain`
OLD_IP=`cat ~/Dropbox/IP.txt`

if [ "$NEW_IP" != "$OLD_IP" ]
then
        pb_msg "[NEW IP]" ${NEW_IP}
        echo $NEW_IP > ~/Dropbox/IP.txt
fi

I had the issue that the curl command waited and asked for a password. I solved this by putting a ":" directly after -u option.
