颜色控制
一、添加颜色
1、终端中的颜色由ANSI转义码控制。ANSI转义码使用CSI（控制序列指示器）开头。
2、CSI的格式：CSInm （m，转义码）（n，显示控制），一个CSI中可包含多个n，使
用“；”号隔开。
n颜色控制码：0 黑色，1 红色，2 绿色，3 ×××，4蓝色，5 洋红色，6 青色，7 白色。
3、前景色与背景色：CSIvnm（v应用值，3前景色，4背景色）
CSI47m;30m
4、CSI的表示方法：^[[ (^[ ctrl+v esc)
^[[0m 未设置状态
＃echo "^[[CSI值"
示例：修改界面颜色：＃echo “^[[CSI颜色值”
修改输出文字背景：＃echo "^[[41mthis is a test"；echo "^[[0m"
#echo "^[[42;33mthis is a test^[[0m"
