 1 | # Apt-update-mailer
 2 | 
 3 | This is a bash script which can be ran from a cronjob. It mails which packages can be updated, the current version you have installed, the version you are updating to and (on an ubuntu system) an URL to the Ubuntu package archive with more info on the update. If there are no updates, you won't get an email.

30 | ## Installation
31 | 
32 | Create a folder for the scripts (doesn't need to be root):
33 | 
34 |     mkdir ~/scripts
35 | 
36 | Place the script there (or git clone the repo):
37 | 
38 |     nano ~/scripts/apt-update-mailer.sh
39 | 
40 | Make it executable:
41 | 
42 |     chmox +x ~/scripts/apt-update-mailer.sh
43 | 
44 | Add the cronjob:
45 |     
46 |     crontab -e
47 |     # [ADD, CHECKS ONCE A DAY AT 01:01 AM]
48 |     1 1 * * * ~/scripts/updatemail.sh
49 | 
50 | If you don't receive any emails it either means the script did not find any updates, or that your MTA is not setup correctly. Check /etc/aliases, the postfix/sendmail installation and the cron email address.
