Last active December 19, 2015 10:19
Simple URL checker. All it does is check a predefined url to see if it has changes over the time. If it did , then it sends you an e-mail. It is useful when your are waiting for something on a website to change!
#!/usr/bin/perl -W
use strict;
use warnings;
use LWP::Simple;
use Digest::MD5 qw(md5 md5_hex md5_base64);
use Encode qw(encode_utf8);
my $link = [URL TO BE CHECKED];
my $email_from = [FROM EMAIL];
my $email = [TO EMAIL];

/*
* StravaMerger © David Gouveia - http://www.davidgouveia.net
* Simple script to merge tracking data from Strava's exported GPX files.
* The backtrack_limit is there because some files could not be parsed due to their size.
* Feel free to raise the limit but be carrefull not to cross the limit.
* Instead of using regex, I could have used a XML cursor to overcome the backtrack limit
* but either I would have to use the php_xml extension or build my own parser.
