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

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。

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：

如果您使用zsh或bash

black() {
    echo -e "\e[30m${1}\e[0m"
}

red() {
    echo -e "\e[31m${1}\e[0m"
}

green() {
    echo -e "\e[32m${1}\e[0m"
}

yellow() {
    echo -e "\e[33m${1}\e[0m"
}

blue() {
    echo -e "\e[34m${1}\e[0m"
}

magenta() {
    echo -e "\e[35m${1}\e[0m"
}

cyan() {
    echo -e "\e[36m${1}\e[0m"
}

gray() {
    echo -e "\e[90m${1}\e[0m"
}

black 'BLACK'
red 'RED'
green 'GREEN'
yellow 'YELLOW'
blue 'BLUE'
magenta 'MAGENTA'
cyan 'CYAN'
gray 'GRAY'

联机尝试

使用具有setaf功能和参数1的tput。

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

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。
