直接用 zsh + oh-my-zsh 多好..

IPADDRS=ifconfig |grep inet|grep -v "127.0.0.1"|sed -n '2p'|awk '{print $2}'|awk -F ':' '{print $2}'
export PS1="[\033[0m]IP => [\033[1;33m]$IPADDRS [\033[0m]Time:[\033[1;35m]\t [\033[0m]User:[\033[1;33m]\u [\033[0m]History:[\033[1;33m]! [\033[0m]\n $YELLOW\w[$(check_git_changes)]$(parse_git_branch)$LIGHT_GRAY $ "
这样丰富了～
