Episode 9: Redirection and substitution

Command Line TV is a video podcast to help you
    learn and master the Unix shell. Informally, &lsquo;Unix&rsquo; 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&rsquo;s not easy to learn. We&rsquo;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.
