Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2025-03-24: Commenting is disabled permanently. Previous comments are archived at web.archive.org. ]

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.

	This script lists all APT package updates currently available for your system
	along with the version numbers of the old & new packages. It is derived from
	``/usr/lib/update-notifier/apt-check`` in the ``update-notifier-common``
	package on Ubuntu 14.04 (Trusty Tahr) and is made available under the same

	This script is know to work on Ubuntu Trusty and Xenial, and it should work on
	any recent version of Ubuntu with the ``python3-apt`` package installed.
