export GIT_PS1_SHOWUNTRACKEDFILES=1
if [ "$PS1" ]; then
  if [ "$BASH" ]; then
    if [ -f /etc/bash.bashrc ]; then
        . /etc/bash.bashrc
    fi
    if [ "`id -u`" -eq 0 ]; then
       PS1='\[\033[01;31m\]\h \[\033[01;34m\]\W \$ \[\033[00m\]'
    else
       PS1='$(__git_ps1 "(%s) ")\[\033[01;32m\]\u@\h \[\033[01;34m\]\w \$ \[\033[00m\]'
    fi
