#22 Redirecting Standard Output and Input
Sometimes it is useful to have what would normally be output to the screen output to a textfile or even elsewhere. Luckily, this is trivial in a POSIX operating system.
In this episode you'll learn how to redirect Standard Output into more than just textfiles and how this can be used with a variety of of utilities.

#17 Hello Zsh! Part 2
In the second half of our 2 part series on Zsh, we look at globbing and using Zsh's qualifiers. This can be combined with the completion from episode 16 for some super powerful shell bliss.

#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.

#15 Power Searching with Ack
Most Linux/Unix users are familiar with Grep, but for many situations Ack does a better and faster job.
Ack is smart enough to skip version control files and directories, temp files, can exclude or include certain file types, and use powerful regular expression when searching.

This week we take a peek at GNU Screen - a terminal multiplexer. GNU Screen allows you to open multiple terminal sessions and easily switch between them from one terminal window. You can also disconnect from GNU Screen and your terminal sessions will stay in the background waiting for you to reconnected.

#12 Getting Started with Iptables
Iptables is the de-facto firewall solution for Linux. In this episode, we'll setup basic rules to only allow certain traffic and even deny certain IP addresses from connecting.
NOTE: I did catch one minor error in the screencast after encoding - I mention iptables in conjunction with both Linux and Unix. Iptables has many hooks into the Linux kernel and therefore is not available for Unix. Sorry for any confusion.

#8 Customizing Your Bash Command Prompt
The Bash command prompt can be fairly dull by default.
In this episode we add some color to help differentiate between files, executables, symlinks, and directories. We'll also change the format of the command prompt with the current time and better formatting.
