    1. Linux 下如何使用命令echo打印出有颜色的内容?
      -->文字颜色:
    # syntax: echo -e "\033[1;颜色码+m some_text \033[0m"
    echo -e "\033[1;31mThis is red text\033[0m"
    This is red text
    

    \033[:告诉终端后面是设置颜色的参数
    \033[1;31m:将颜色设置为红色
    \033[0m:将颜色恢复初始设置
    文字颜色码
    0:恢复初始设置;30:黑;31:红色;32:绿色;33:黄色;34:蓝色;35:洋红;36:青色;37:白色
    -->背景颜色:

    echo -e "\033[1;42mGreed Background\033[0m"
    

    Greed Background颜色码
    0:恢复初始设置;40:黑;41:红色;42:绿色;43:黄色;44:蓝色;45:洋红;46:青色;47:白色
    -->文字闪动:

    echo -e "\033[37;31;5mMySQL Server Stop...\033[39;49;0m"
    

    红色数字处还有其他数字参数:0 关闭所有属性、1 设置高亮度(加粗)、4 下划线、5 闪烁、7 反显、8 消隐
