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。

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

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

到目前为止，我最喜欢的答案是彩色回声。

为了发布另一个选项，您可以查看这个小工具xcol

https://ownyourbits.com/2017/01/23/colorize-your-stdout-with-xcol/

您可以像grep一样使用它，例如，它会为每个参数用不同的颜色来着色其stdin

sudo netstat -putan | xcol httpd sshd dnsmasq pulseaudio conky tor Telegram firefox "[[:digit:]]+\.[[:digit:]]+\.[[:digit:]]+\.[[:digit:]]+" ":[[:digit:]]+" "tcp." "udp." LISTEN ESTABLISHED TIME_WAIT

注意，它接受sed将接受的任何正则表达式。

此工具使用以下定义

#normal=$(tput sgr0)                      # normal text
normal=$'\e[0m'                           # (works better sometimes)
bold=$(tput bold)                         # make colors bold/bright
red="$bold$(tput setaf 1)"                # bright red text
green=$(tput setaf 2)                     # dim green text
fawn=$(tput setaf 3); beige="$fawn"       # dark yellow text
yellow="$bold$fawn"                       # bright yellow text
darkblue=$(tput setaf 4)                  # dim blue text
blue="$bold$darkblue"                     # bright blue text
purple=$(tput setaf 5); magenta="$purple" # magenta text
pink="$bold$purple"                       # bright magenta text
darkcyan=$(tput setaf 6)                  # dim cyan text
cyan="$bold$darkcyan"                     # bright cyan text
gray=$(tput setaf 7)                      # dim white text
darkgray="$bold"$(tput setaf 0)           # bold black = dark gray text
white="$bold$gray"                        # bright white text

我像这样在脚本中使用这些变量

echo "${red}hello ${yellow}this is ${green}coloured${normal}"

使用tput计算颜色代码。避免使用ANSI转义码（例如，\e[31；1m表示红色），因为它不易移植。例如，OS X上的Bash不支持它。

BLACK=`tput setaf 0`
RED=`tput setaf 1`
GREEN=`tput setaf 2`
YELLOW=`tput setaf 3`
BLUE=`tput setaf 4`
MAGENTA=`tput setaf 5`
CYAN=`tput setaf 6`
WHITE=`tput setaf 7`

BOLD=`tput bold`
RESET=`tput sgr0`

echo -e "hello ${RED}some red text${RESET} world"

red='\e[0;31m'
NC='\e[0m' # No Color
echo -e "${red}Hello Stackoverflow${NC}"

这个答案是正确的，只是对颜色的调用不应该在引号内。

echo -e ${red}"Hello Stackoverflow"${NC}

应该会成功的。
