Actually, aptitude and apt-get are very similar (at least at the
command line) front-ends for dpkg - aptitude never calls apt-get.

Derek, in my normally picky-picky mode I would make this comment.
Aptitude is a front end for apt which was crafted as a front end for
dpkg.

I challenge you to ever find an instance of aptitude running a command
named "apt". In fact, "apt" is a java tool on my system. "apt" is a
catch-all word for the whole Advanced Package Tool. apt-get isn't a
"front-end" for apt - it IS the command line component of the apt package.

Apt-get
is a command line tool for apt and aptitude is a terminal based front
end for apt. Minor difference from what you wrote, but, strictly
speaking, more precise.

More precise, but essentially wrong. Aptitude _has_ a terminal based
front-end, but it's perfectly possible to use it almost exactly as you use
apt-get. When it comes down to running other binaries, what they both
execute is "dpkg" - just watch the process tree.

You are correct that I should have written APT.

No, of course there is no command apt but try uninstalling the package apt
and see if those CLI commands work with dpkg.

From the description of apt:
"Advanced front-end for dpkg
This is Debian's next generation front-end for the dpkg package manager.
It provides the apt-get utility and APT dselect method that provides a
simpler, safer way to install and upgrade packages.

APT features complete installation ordering, multiple source capability
and several other unique features, see the Users Guide in apt-doc."

I don't think it is an accident that the CLI tool apt-get starts with the
letters "a", "p", "t". Nor do I think that it is an accident the terminal
interface aptitude (which you correctly state can also work as a CLI
command similar to apt-get) starts with "apt".

Here is the description for aptitude:
"terminal-based apt frontend
aptitude is a terminal-based apt frontend with a number of useful
features, including: a mutt-like syntax for matching packages in a
flexible manner, dselect-like persistence of user actions, the
ability to retrieve and display the Debian changelog of most
packages, and a command-line mode similar to that of apt-get."

YMMV.
