这些代码在我的Ubuntu盒子上运行：

echo -e "\x1B[31m foobar \x1B[0m"
echo -e "\x1B[32m foobar \x1B[0m"
echo -e "\x1B[96m foobar \x1B[0m"
echo -e "\x1B[01;96m foobar \x1B[0m"
echo -e "\x1B[01;95m foobar \x1B[0m"
echo -e "\x1B[01;94m foobar \x1B[0m"
echo -e "\x1B[01;93m foobar \x1B[0m"
echo -e "\x1B[01;91m foobar \x1B[0m"
echo -e "\x1B[01;90m foobar \x1B[0m"
echo -e "\x1B[01;89m foobar \x1B[0m"
echo -e "\x1B[01;36m foobar \x1B[0m"

这将以不同的颜色打印字母a、b、c、d：

echo -e "\x1B[0;93m a \x1B[0m b \x1B[0;92m c \x1B[0;93m d \x1B[0;94m"

对于循环：

for (( i = 0; i < 17; i++ )); 
do echo "$(tput setaf $i)This is ($i) $(tput sgr0)"; 
done

要显示具有不同颜色的消息输出，可以执行以下操作：

echo -e "\033[31;1mYour Message\033[0m"

-黑色0；30深灰色1；30-红色0；31浅红色1；31-绿色0；32浅绿色1；32-棕色/橙色0；33黄色1；33-蓝色0；34浅蓝色1；34-紫色0；35浅紫色1；35-青色0；36浅青色1；36-浅灰色0；37白色1；37

echo -e "\033[31m Hello World"

[31m控制文本颜色：

30-37套前景色40-47套背景色

这里可以找到更完整的颜色代码列表。

最好将字符串末尾的文本颜色重置回\033[0m。

我对托拜厄斯回答的重复：

# Color
RED='\033[0;31m'
GREEN='\033[0;32m'
YELLOW='\033[0;33m'
NC='\033[0m' # No Color

function red {
    printf "${RED}$@${NC}\n"
}

function green {
    printf "${GREEN}$@${NC}\n"
}

function yellow {
    printf "${YELLOW}$@${NC}\n"
}

其他的答案已经很好地解释了如何做到这一点。我仍然缺少的是对颜色代码的一个精心安排的概述。维基百科文章“ANSI转义码”对此非常有用。然而，由于颜色通常可以在每个终端中进行配置，并且看起来不同，所以我更希望有一个可以在终端中调用的功能。为此，我创建了以下函数来显示颜色表，并提醒我如何设置它们（排列方式受wiki文章的启发）。例如，您可以将它们加载到.bashrc/.zshrc中，或将它们作为脚本放在某处。

使用具有setaf功能和参数1的tput。

echo "$(tput setaf 1)Hello, world$(tput sgr0)"
