Tabs in linux console.

Why?

  • Everything is save if you loose connection.
  • You can have only one ssh/putty window opened.

SSH

  • Use SSH Keys - they are awesome! (especially for github)

Shell

Zsh

Awesome and pretty configurable shell. If you hate configs try oh-my-zsh. Or I can provide you my .zshrc config file.

Fish

Great and easy shell. No need to configure anything! Just try it!

Debug

pretty print

require 'pp'

a = {:ahoj => 1, :neco => 2}
pp a

irb

Let's move to pry.

pry

Interactive ruby console.

require 'pry'

a = 'hello'
binding.pry
