为了进一步解释这个答案，对于我们这些懒惰的人来说：

function echocolor() { # $1 = string
    COLOR='\033[1;33m'
    NC='\033[0m'
    printf "${COLOR}$1${NC}\n"
}

echo "This won't be colored"
echocolor "This will be colorful"

灵感来自@nachoparker的回答，我的.bashrc中有这个：

#### colours
source xcol.sh

### tput foreground
export tpfn=$'\e[0m' # normal
export tpfb=$(tput bold)

## normal colours
export tpf0=$(tput setaf 0) # black
export tpf1=$(tput setaf 1) # red
export tpf2=$(tput setaf 2) # green
export tpf3=$(tput setaf 3) # yellow
export tpf4=$(tput setaf 4) # blue
export tpf5=$(tput setaf 5) # magenta
export tpf6=$(tput setaf 6) # cyan
export tpf7=$(tput setaf 7) # white
# echo "${tpf0}black ${tpf1}red ${tpf2}green ${tpf3}yellow ${tpf4}blue ${tpf5}magenta ${tpf6}cyan ${tpf7}white${tpfn}"

## bold colours
export tpf0b="$tpfb$tpf0" # bold black
export tpf1b="$tpfb$tpf1" # bold red
export tpf2b="$tpfb$tpf2" # bold green
export tpf3b="$tpfb$tpf3" # bold yellow
export tpf4b="$tpfb$tpf4" # bold blue
export tpf5b="$tpfb$tpf5" # bold magenta
export tpf6b="$tpfb$tpf6" # bold cyan
export tpf7b="$tpfb$tpf7" # bold white
# echo "${tpf0b}black ${tpf1b}red ${tpf2b}green ${tpf3b}yellow ${tpf4b}blue ${tpf5b}magenta ${tpf6b}cyan ${tpf7b}white${tpfn}"

出口允许我使用这些tpf。。在Bash脚本中。

您可以“组合”颜色和文本模式。

#!/bin/bash

echo red text / black background \(Reverse\)
echo "\033[31;7mHello world\e[0m";
echo -e "\033[31;7mHello world\e[0m";
echo

echo yellow text / red background
echo "\033[32;41mHello world\e[0m";
echo -e "\033[32;41mHello world\e[0m";
echo "\033[0;32;41mHello world\e[0m";
echo -e "\033[0;32;41mHello world\e[0m";
echo

echo yellow BOLD text / red background
echo "\033[1;32;41mHello world\e[0m";
echo -e "\033[1;32;41mHello world\e[0m";
echo

echo yellow BOLD text underline / red background
echo "\033[1;4;32;41mHello world\e[0m";
echo -e "\033[1;4;32;41mHello world\e[0m";
echo "\033[1;32;4;41mHello world\e[0m";
echo -e "\033[1;32;4;41mHello world\e[0m";
echo "\033[4;32;41;1mHello world\e[0m";
echo -e "\033[4;32;41;1mHello world\e[0m";
echo

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

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"
}
