An attempt to write a script to notify when a movie is listed online for booking

This is my attempt to write a shell script that sends me an email when a movie is available for booking online.

NOTE: You might want to configure 'mail' command SMTP settings on your box to avoid the mail being sent to your spam folder.

This script takes 2 arguments. The first argument is the URL that has to be monitored and the second argument is name of the theater (Or anything that is unique to that theater).

The script scrapes the URL page once in a given interval period and looks for the theater name, and when it's found it sends an email to the given email ID.


#! /bin/bash

if [ "$#" -ne 2 ]; then

    echo "Illegal number of parameters"

    echo "USAGE: movieAlert <URL> <KEYWORD>"

    exit 1

fi

EMAIL_IDS="username@mail.com"

BODY=$1

SUB="Hurry up!!!"

IP=$1

QUERY=$2

while true; do

    result=`wget -O - $IP -o /dev/null|grep $QUERY|wc -l`

    if [ $result -gt 1 ]; then

        mail -s "$SUB" "$EMAIL_IDS" <<<"$BODY"

        exit 0

    fi

    sleep 60

done
