zsh- a shell for humans

@juandebravo

First goal: this prompt

• Is it a new shell? No… it’s been there since 1990!

• It’s newer than bash? Well… less than a year (bash was born in 1989)!

• why has it become popular? Due to oh-my-zsh

How to install

# Debian/Ubuntu!

> sudo apt-get install zsh!

# Mac OS X!

> brew info zsh!

> brew install --disable-etcdir zsh

Set as default shell

> chsh -s $(which zsh)
