This script is a cron-apt-like shell script.

Comparison

What is similar ?

• I want the script check if some updates are available
• I want the script download the package (to be ready to install)
• I want the script send me an email

What is different ?

• I want a verbose email content about available updates
• I don't want receive an email when there is nothing to do
• I want summary information in the subject

The problem

A verbose configuration of cron-apt means receiving email each day. cron-apt does not provide info in the subject.

My solution

Summary legend

• ~ means change : upgraded package
• + means new : newly installed package
• - means remove : removed package

Sample

MAILTO=root /path/to/bin/cronapt.sh

Will send an email like

Subject: CRON-APT: available updates [~1/+0/-0]

Inst linux-libc-dev [3.16.36-1+deb8u1] (3.16.36-1+deb8u2 Debian-Security:8/stable [amd64])
Conf linux-libc-dev (3.16.36-1+deb8u2 Debian-Security:8/stable [amd64])
