awk doesn't recognize '\e' as a code for the escape character. Here's a workaround (something more elegant may exist):
awk不会将'\ e'识别为转义字符的代码。这是一种解决方法(可能存在更优雅的东西):
# Decimal 27 is the ASCII codepoint for the escape character
awk '{ printf "%c[1;32m foo\n", 27 }' <<<foo

\033[?m properly quoted gives colour:
\ 033 [?m正确引用给出颜色:
awk 'BEGIN{ print "\033[34msomething in colour\033[0m";}'
notice how one needs to unescape $1 below:
注意下面需要如何使用$ 1:
echo something | awk '{ print "\033[34m"$1" in colour \033[0m";}'

awk 'BEGIN{print "^[[1;33mYELLOW"}'
would print string YELLOW in yellow (color)
会打印黄色的字符串YELLOW(颜色)
NOTE the first ^[ you have to type ctrl-v then ESC
注意第一个^ [你必须输入ctrl-v然后ESC
I would add a screen shot to show.
我会添加一个屏幕截图来显示。
the above screenshot showed it worked under zsh and bash.
上面的截图显示它在zsh和bash下工作。

As you can see, the functions and various initialization makes it possible to write quite a simple print line as below.
如您所见,功能和各种初始化使得编写如下简单的打印行成为可能。
print colour("Red")$1colour("Blue")$0colour("None");
For the colour function, you may either pass in the integer value of colour or the name. It takes params in the below formats.
对于颜色函数,您可以传入颜色的整数值或名称。它采用以下格式的参数。
colour( <attribute> , <background-colour> , <foreground-colour> )
colour( <background-colour> , <foreground-colour> )
colour( <foreground-colour> )
You can selectively give the required params.
您可以有选择地提供所需的参数。
function isnumeric(x)
{
return ( x == x+0 );
}
function name_to_number(name, predefined)
{
if (isnumeric(name))
return name;
if (name in predefined)
return predefined[name];
return name;
}
function colour(v1, v2, v3)
{
if (v3 == "" && v2 == "" && v1 == "")
return;
if (v3 == "" && v2 == "")
return sprintf("%c[%dm", 27, name_to_number(v1, fgcolours));
else if (v3 == "")
return sprintf("%c[%d;%dm", 27, name_to_number(v1, bgcolours), name_to_number(v2, fgcolours));
else
return sprintf("%c[%d;%d;%dm", 27, name_to_number(v1, attributes), name_to_number(v2, bgcolours), name_to_number(v3, fgcolours));
}
BEGIN {
# hack to use attributes for just "None"
fgcolours["None"] = 0;
