From 9055d5e68bd09f31df00e45bd14cb599ba3735e5 Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Mon, 26 Oct 2015 19:30:44 +0100 Subject: hidden support more apt-get/apt-cache commands in apt MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit apt is supposed to be a user-friendly interface, so while these commands are usually poweruser material and therefore do not need to be shown in general introduction manpages/help messages its of no use to not allow users to use them. This includes clean, autoclean, build-dep, source, download, changelog, depends, rdepends and showsrc – it doesn't include more non-interactive commands like dump or xvcg as those are usually used by scripts if at all.
