About
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!
