#apt-check.sh

A re-implimentation of some of the functionality of update-notifier-common in POSIX shell

Debian and Ubuntu have or did have a package called update-notifier-common that did some stuff so you could have this sort of thing in your message of the day etc.

28 packages can be updated.
16 updates are security updates.

This script aims to impliment some of the functionality of the /usr/lib/update-notifier/apt-check without depending on python.

Usage

./apt-check.sh [OPTIONS]

Outputs upgrade information to stderr.

Options

Flag	Option	Description
-h	Human Readable	set this option to get MOTD style output.
-f	Fussy	set this option to make the exit status more fussy. When set a non zero exit status is returned if any packages are avalible for upgrading, if unset a non zero exit status is returned if any packages have security upgades avalible.
-q	Quiet	hides the output if there are no packages to upgrade, respects the fussy option.
-s	Skip Update	Does not run apt-get update before testing, saves a few seconds if you are running apt-get update periodicly in some other context.
-c	Cleanup	Runs apt-get clean and cleanup /var/lib/apt/lists/* useful for saving diskspace in the context of building a docker image etc.

Example Installation

Dependencies

• A POSIX /bin/sh
  • test
  • cut
  • grep
• apt-get

Testing

The automated test suite tests against:

• Ubuntu
  • 14.04 LTS - Trusty
  • 12.04 LTS - Precise
• Debian
  • sid - unstable
  • jessie - testing
  • wheezy - stable

To run the test suite you will need ruby and docker.

bundle install
bundle exec rspec

The os images used in these tests can be found here. Note that as these need to be downloaded to run the tests that the first run may be quite slow and use up some diskspace.
