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

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。

以下是我最终使用sed的结果

echo " [timestamp] production.FATAL Some Message\n" \
"[timestamp] production.ERROR Some Message\n" \
"[timestamp] production.WARNING Some Message\n" \
"[timestamp] production.INFO Some Message\n" \
"[timestamp] production.DEBUG Some Message\n"  | sed \
-e "s/FATAL/"$'\e[31m'"&"$'\e[m'"/" \
-e "s/ERROR/"$'\e[31m'"&"$'\e[m'"/" \
-e "s/WARNING/"$'\e[33m'"&"$'\e[m'"/" \
-e "s/INFO/"$'\e[32m'"&"$'\e[m'"/" \
-e "s/DEBUG/"$'\e[34m'"&"$'\e[m'"/"

打印方式如下：

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

这是我过去看到的所有组合，并决定哪一个读起来很酷：

for (( i = 0; i < 8; i++ )); do
    for (( j = 0; j < 8; j++ )); do
        printf "$(tput setab $i)$(tput setaf $j)(b=$i, f=$j)$(tput sgr0)\n"
    done
done

为了可读性

如果要提高代码的可读性，可以先回显字符串，然后使用sed添加颜色：

echo 'Hello World!' | sed $'s/World/\e[1m&\e[0m/'
