Command Line TV is a video podcast to help you
learn and master the Unix shell. Informally, ‘Unix’ refers to a
family of
operating systems that includes GNU/Linux, Mac OS X, and FreeBSD. Operating
a computer via the command line gives you tremendous power and flexibility,
but it’s not easy to learn. We’re here to help! We start from the
beginning, but also try to include some tips suitable for intermediate
users. Each video is about 20 minutes long, and we aim to release a new
episode every week or so.

Episode 8: Package managers
In this episode, we explore some of the capabilities of package managers for
installing and updating software on your system. Specifically, we look at the
‘apt’ system on Ubuntu GNU/Linux. On other systems, you might use Yum
(RedHat/Fedora), Pacman (Arch), or Homebrew (Mac). This page shows a comparison
of commands for several Linux packaging systems:

We look at ImageMagick, a powerful suite of command-line tools for doing image
processing. With it, we resize, crop, blur, and do format-conversion on a
collection of image files.
