颜色设置
颜色设置示例
echo -e "\033[41;37;5m Hello \033[0m world"
echo -e "\E[41;37;5m Hello \E[0m world"
echo -e "\e[41;37;5m Hello \e[0m world"
# \033 等同于 \E 等同于 \e
以上命令设置背景成为红色，前景白色，闪烁光标，输出字符 "Hello"，然后重新设置屏幕到缺省设置，输出字符 "world"。"-e"是命令 echo 的一个可选项，它用于激活特殊字符的解析器。"\033"引导非常规字符序列。"m"意味着设置属性然后结束非常规字符序列，这个例子里真正有效的字符是 "41;37;5" 和"0"。修改"41;37;5"可以生成不同颜色的组合，数值和编码的前后顺序没有关系。

param result
0 reset all attributes to their defaults
1 set bold
2 set half-bright (simulated with color on a color display)
4 set underscore (simulated with color on a color display)
(the colors used to simulate dim or underline are set
using ESC ] ...)
5 set blink
7 set reverse video
10 reset selected mapping, display control flag, and toggle
meta flag (ECMA-48 says "primary font").
11 select null mapping, set display control flag, reset tog‐
gle meta flag (ECMA-48 says "first alternate font").
12 select null mapping, set display control flag, set toggle
meta flag (ECMA-48 says "second alternate font"). The
toggle meta flag causes the high bit of a byte to be tog‐
gled before the mapping table translation is done.
