    Moving to Zsh

Have a good time with bash for a long while, it's time to try another tempting shell - Zsh. So, this Gist is nothing but my collection for the environment that I've searched and applied to my system. There is also this kind of Gist in a version of bash.
Why Zsh?

There are several shells out there but this is the one that is close to the bash with some useful and attractive features especially - yes, theme. Here are some good articles about how and why to choose Zsh over bash, enjoy trying!

Zsh is your friend

and this (I may soon leave Oh-My-Zsh to try this)

Ditching Oh-my-zsh for Prezto

Dependencies


Zsh -- built-in on OSX but better reinstall for the newer version
Oh-My-Zsh -- Zsh configuration framework
tmux -- terminal multiplexor
reattach-to-user-namespace -- for tmux being able to copy to clipboard
vim -- built-in on OSX but better for the newer version
spf13 -- distribution of vim plugins
youtube-dl -- youtube download script

Installation

brew install zsh # Zsh
sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)" # Oh-My-Zsh
brew install tmux # tmux
brew install reattach-to-user-namespace # tmux patch
brew install vim # editor
curl http://j.mp/spf13-vim3 -L -o - | sh # spf13
brew install youtube-dl # add-on
Configuration

The files that will be added and edited are all in home directory ( ~ ) as following:

~/.zshrc
~/.custom-bash
~/.tmux.conf

.zshrc

By installing Oh-My-Zsh, there is nothing to do other than adding your preferred Zsh plugins and your personal aliases. For that, I choose to separate my aliases in another files and source in .zshrc instead.
# at around line 52
# I only need 2 plugins now.. lol

.tmux.conf

Custom modification for tmux. By default tmux uses C-b as prefix which is pretty annoying for me (too lazy to C-b), so I change it to ` for the sake of laziness. Note that this config is modified like this just because I like it this way - there is no principle to limit creativity.
Many key bindings have been changed in this config (mixed from sources below). If want to know which key mapped with which command, it can be checked by ` + ?.
Note that there is difference in Mac OS X and Linux(es) in term of copy & paste buffer.

There is no GitHipster (completion and highlighting) here?

No, there is not. The reason is that Zsh supports git almost out of the box, plus with Oh-My-Zsh, it's good to go instantly without any help from git-completion script like in bash. Attached image below is the example of how git repo looks like for default Oh-My-Zsh theme.
