Недавно научился делать вот так:

echo -en "\e[33;44m"<--><------><------># bacground to blue
echo "-----------------------------"
echo "Report"
echo -e "Stack Pointer = \e[1;34m$SP"<-># Colot set to blue
tput sgr0<-----><------><------><------># terminal restored
echo -en "\e[33;44m"
echo -e "last element = \e[1;31m$data" ># Color set to red
tput sgr0<-----><------><------><------># terminal restored
echo -en "\e[33;44m"
echo -n "-----------------------------"
tput sgr0<-----><------><------><------># terminal restored

Что это дает?
А вот что…

Цветной вывод сообщений в консоли. Удобочитаемость повышается в разы.

Полезность не велика, но у меня несколько применений есть.

Это ANSI escape-последовательности. Задаются следующим синтаксисом.

echo -e '\e[col1;col2m выводимый текст'

-e обязательный ключ
-e enable interpretation of backslash escapes

\e[ — начало escape-последовательности.
col1 и col2, цвет символов и цвет фона соответственно.

Числовые значения цвета в escape-последовательностях

Цвет Текст Фон
черный 30 40
красный 31 41
зеленый 32 42
желтый 33 43
синий 34 44
пурпурный 35 45
зеленовато-голубой 36 46
белый 37 47

Синтаксис вообще ни разу не юзерфрендли.
Для решения такой проблемы я использовал переменные.


тогда становится гораздо проще подцвечивать консоль.

вот так можно попробовать:

green='\e[1;32m' && echo -e "${green}"`uname -a`
