screen

改一下 ~/.bashrc

GITPS1='$(__git_ps1 " (%s)")'

case "$TERM" in
xterm*|rxvt*)

    PS1="${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]${GITPS1}\$ "
    PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1"
    ;;
screen*)
    PS1="${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]${GITPS1}\$ "
    PATHTITLE='\[\ek\W\e\\\]'
    # Use program name as title
    PROGRAMTITLE='\[\ek\e\\\]'
    PS1="${PROGRAMTITLE}${PATHTITLE}${PS1}"
    ;;
*)
    ;;
esac

小抄一下別人的 ~/.screenrc
