Answer 1

1- If you don't have bash-completion ... : sudo apt-get install bash-completion

2- Edit your .bashrc file and check (or add) :

if [ -f /etc/bash_completion ]; then
  . /etc/bash_completion
fi

3- ... before your prompt line : export PS1='$(__git_ps1) \w\$ '
(__git_ps1 will show your git branch)

4- do source .bashrc
