Customizing your shell prompt

Shell prompts are extremely customizable. You can customize them in two ways: (1) by using command characters that print out special things and (2) by using colors. Also, customizing the prompt is different in different shells; I'm going to cover tcsh and zsh here. bash is the other popular shell, but I think it sucks, and I never use it, so I'm not going to waste any time on it.

tcsh
zsh
tcsh

I'll start with tcsh, since it's the default BSD and Mac OS X shell. Here's a very simple prompt:

# Instalando o Ruby no RVM
rvm install 2.0.0-p451

# Criando uma gemset e instalando o Rails
rvm gemset create rails_4_0_5
rvm 2.0.0-p451@gastos_rails_4_0_5 #usando a gemset com a versão do ruby instalada
gem install rails -v 4.0.5

# Verificando se tudo foi ok
ruby -v

# Description: Replaces the HOSTS file with a customized version (hosts-file.net) that blocks
# domains that serve ads and malicious software, creating a backup of the old
# file.
# Improvements: Add the partial file, a /etc/hosts_dev with some development hosts and creates 
# a logfile

Configure the proxy settings in the .bashrc
If you want set the proxy for all the users you can do it in the system wide .bashrc file.
sudo vi /etc/bash.bashrc

#proxy settings
export http_proxy=http://DOMAIN\USERNAME:PASSWORD@SERVER:PORT/
export ftp_proxy=http://DOMAIN\USERNAME:PASSWORD@SERVER:PORT/

Additionally if you want APT to use a proxy server you can configure it in the /etc/apt/apt.conf configuration file.
sudo vi /etc/apt/apt.conf
