Email one or many people when a twitter account hasn't been updated in the last hour.

tweetcheck.sh

#!/bin/sh
#
# NOTE: Twitter updated their m.twitter site January 2013, and this script doesn't work anymore.
#
# This script is useful for alerting a team of people when a twitter account
# hasn't been updated in the past hour. There may be other uses as well.
#
# $1 = what account to check
# $2 = what string to look for. To test the script, use 'test'
#
# FILE: emails
# Email addresses (each on its own line) in a file 'emails' will be alerted
# if the string we're looking for isn't on the page.
#
# FILE: note
# The message emailed is contained in a file 'note'
#
# To see a typical page it's scraping, go to https://mobile.twitter.com/denverpost
#
# Example: ./tweetcheck.sh denverpost m
