PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[01;33m\]$(__git_ps1 " (%s)")\[\033[00m\]\$ '

PS1='${debian_chroot:+($debian_chroot)}\[\033[01;34m\]\w\[\033[01;33m\]$(__git_ps1 " (%s)")\[\033[00m\]\$ '
It rids of the user and hostname which I obviously know and need not print all the time.
