How do I install the Z shell ( zsh ) shell under FreeBSD 9 operating systems?
The Z shell (zsh) is a Unix shell and command interpreter for shell scripting. Zsh can be thought of as an extended Bourne shell with a large number of improvements, including some features of bash, ksh, and tcsh.

You need to use chsh command to change your default shell under Unix like operating system:

$ cat ~/.zshrc
HISTFILE=~/.histfile HISTSIZE=1000 SAVEHIST=1000 setopt appendhistory autocd extendedglob unsetopt beep bindkey -e
Because zsh contains many features, I recommend that you go through the zsh manual page which has been split into a number of sections:
