我们开发就是喜欢各种酷炫的东西，对于有洁癖的我，连命令行都不放过了

先上图看效果，命令行显示高亮部分

实现过程：

第一步：.bash_prompt脚本  


# ~/.bash_prompt
# This prompt inspired by gf3, sindresorhus, alrra, and mathiasbynens.
# but customized to me. <3

default_username='paulirish'


#eval "$(thefuck --alias)"


if [[ -n "$ZSH_VERSION" ]]; then  # quit now if in zsh
    return 1 2> /dev/null || exit 1;
fi;


if [[ $COLORTERM = gnome-* && $TERM = xterm ]] && infocmp gnome-256color >/dev/null 2>&1; then
    export TERM=gnome-256color
elif infocmp xterm-256color >/dev/null 2>&1; then
    export TERM=xterm-256color
fi


set_prompts() {

}



set_prompts
unset set_prompts


第二步：加入bash_profile

$ vim ~/.bash_profile
## add code to buttom
[[ -s $HOME/.bash_prompt ]] && source $HOME/.bash_prompt


重新打开命令行 或者执行 source ~/.bash_profile  就可以看到效果了，是不是非常炫呀
