Hello Zsh! Part 1 - Linux and Open Source Screencasts

#16 Hello Zsh! Part 1

Zsh is a great alternative to Bash and other Unix shells. It has programmable completion, paging, and many other great features.

We'll take a good look at paging and the completion that Zsh offers in this episode and explore more in the next episode.

As mentioned in the episode, the Zsh Wiki is an excellent source for Zsh information and help with your .zshrc.
