您可以使用这些ANSI 转义码：

Black        0;30     Dark Gray     1;30
Red          0;31     Light Red     1;31
Green        0;32     Light Green   1;32
Brown/Orange 0;33     Yellow        1;33
Blue         0;34     Light Blue    1;34
Purple       0;35     Light Purple  1;35
Cyan         0;36     Light Cyan    1;36
Light Gray   0;37     White         1;37

然后在你的脚本中像这样使用它们：

#    .---------- constant part!
#    vvvv vvvv-- the code from above
RED='\033[0;31m'
NC='\033[0m' # No Color
printf "I ${RED}love${NC} Stack Overflow\n"

以红色打印love。

根据@james-lim 的评论，如果您使用该echo命令，请务必使用 -e 标志来允许反斜杠转义。

# Continued from above example
echo -e "I ${RED}love${NC} Stack Overflow"

"\n"（使用时请勿添加，echo除非您想添加额外的空行）

您可以使用 awesometput命令（在Ignacio 的回答中建议）为各种事物生成终端控制代码。

用法

具体tput的子命令将在后面讨论。

直接的

tput作为命令序列的一部分调用：

tput setaf 1; echo "this is red text"

如果文本仍然显示错误，请使用;而不是。&&tput

外壳变量

另一种选择是使用 shell 变量：

red=`tput setaf 1`
green=`tput setaf 2`
reset=`tput sgr0`
echo "${red}red text ${green}green text${reset}"

tput产生被终端解释为具有特殊含义的字符序列。他们不会自己显示出来。请注意，它们仍然可以保存到文件中或由终端以外的程序作为输入处理。

命令替换

使用命令替换tput将's 的输出直接插入echo字符串可能更方便：

echo "$(tput setaf 1)Red text $(tput setab 7)and white background$(tput sgr 0)"

例子

上面的命令在 Ubuntu 上产生这个：

彩色终端文字截图

前景色和背景色命令

tput setab [1-7] # Set the background colour using ANSI escape
tput setaf [1-7] # Set the foreground colour using ANSI escape

颜色如下：

Num  Colour    #define         R G B

0    black     COLOR_BLACK     0,0,0
1    red       COLOR_RED       1,0,0
2    green     COLOR_GREEN     0,1,0
3    yellow    COLOR_YELLOW    1,1,0
4    blue      COLOR_BLUE      0,0,1
5    magenta   COLOR_MAGENTA   1,0,1
6    cyan      COLOR_CYAN      0,1,1
7    white     COLOR_WHITE     1,1,1

还有非 ANSI 版本的颜色设置函数（setb代替setab, 和setf代替setaf）使用不同的数字，这里没有给出。

文本模式命令

tput bold    # Select bold mode
tput dim     # Select dim (half-bright) mode
tput smul    # Enable underline mode
tput rmul    # Disable underline mode
tput rev     # Turn on reverse video mode
tput smso    # Enter standout (bold) mode
tput rmso    # Exit standout mode

光标移动命令

tput cup Y X # Move cursor to screen postion X,Y (top left is 0,0)
tput cuf N   # Move N characters forward (right)
tput cub N   # Move N characters back (left)
tput cuu N   # Move N lines up
tput ll      # Move to last line, first column (if no cup)
tput sc      # Save the cursor position
tput rc      # Restore the cursor position
tput lines   # Output the number of lines of the terminal
tput cols    # Output the number of columns of the terminal

清除和插入命令

tput ech N   # Erase N characters
tput clear   # Clear screen and move the cursor to 0,0
tput el 1    # Clear to beginning of line
tput el      # Clear to end of line
tput ed      # Clear to end of screen
tput ich N   # Insert N characters (moves rest of line forward!)
tput il N    # Insert N lines

其他命令

tput sgr0    # Reset text format to the terminal's default
tput bel     # Play a bell

使用compiz wobbly windows，该bel命令使终端摇晃一秒钟以引起用户的注意。

脚本

tput接受每行包含一个命令的脚本，这些命令在tput退出前按顺序执行。

通过回显多行字符串和管道来避免临时文件：

echo -e "setf 7\nsetb 1" | tput -S  # set fg white and bg red

|-------+-------+---------+---------+------------------------------|

| end   | \e[m  | \x1b[m  | \033[m  | 0 is appended if you omit it |

bash exception:

If you are going to use these codes in your special bash variables

PS0
PS1
PS2 (= this is for prompting)
PS4

you should add extra escape characters so that bash can interpret them correctly. Without this adding extra escape characters it works but you will face problems when you use Ctrl + r for search in your history.

exception rule for bash

You should add \[ before any starting ANSI code and add \] after any ending ones.
Example:
in regular usage: \033[32mThis is in green\033[0m
for PS0/1/2/4: \[\033[32m\]This is in green\[\033[m\]

\[ is for start of a sequence of non-printable characters
\] is for end of a sequence of non-printable characters

Tip: for memorize it you can first add \[\] and then put your ANSI code between them:

\[start-ANSI-code\]
\[end-ANSI-code\]

type of color sequence:

3/4 bit
8 bit
24 bit

Before diving into these colors, you should know about 4 modes with these codes:

1. color-mode

It modifies the style of color NOT text. For example make the color bright or darker.

0 reset
1; lighter than normal
2; darker than normal

This mode is not supported widely. It is fully support on Gnome-Terminal.

2. text-mode

This mode is for modifying the style of text NOT color.

3; italic
4; underline
5; blinking (slow)
6; blinking (fast)
7; reverse
8; hide
9; cross-out

and are almost supported.
For example KDE-Konsole supports 5; but Gnome-Terminal does not and Gnome supports 8; but KDE does not.

3. foreground mode

This mode is for colorizing the foreground.

4. background mode

This mode is for colorizing the background.

Tips and Tricks for Advanced Users and Programmers:

Can we use these codes in a programming language?

Yes, you can. I experienced in bash, c, c++, d perl, python

Do they slow down the speed of a program?

I think, NO.

Can we use these on Windows?

3/4-bit Yes, if you compile the code with gcc
some screen-shots on Win-7

How to calculate the length of code?

\033[ = 2, other parts 1

Where can we use these codes?

Anywhere that has a tty interpreter
xterm, gnome-terminal, kde-terminal, mysql-client-CLI and so on.
For example if you want to colorize your output with mysql you can use Perl

#!/usr/bin/perl -n
print "\033[1m\033[31m$1\033[36m$2\033[32m$3\033[33m$4\033[m" while /([|+-]+)|([0-9]+)|([a-zA-Z_]+)|([^\w])/g;

store this code in a file name: pcc (= Perl Colorize Character) and then put the file a in valid PATH then use it anywhere you like.

ls | pcc
df | pcc

inside mysql first register it for pager and then try:

[user2:db2] pager pcc
PAGER set to 'pcc'
[user2:db2] select * from table-name;

It does NOT handle Unicode.

Do these codes only do colorizing?

No, they can do a lot of interesting things. Try:

echo -e '\033[2K'  # clear the screen and do not move the position

or:

echo -e '\033[2J\033[u' # clear the screen and reset the position

There are a lot of beginners that want to clear the screen with system( "clear" ) so you can use this instead of system(3) call

Are they available in Unicode?

Yes. \u001b

Which version of these colors is preferable?

It is easy to use 3/4-bit, but it is much accurate and beautiful to use 24-bit.
If you do not have experience with html so here is a quick tutorial:
24 bits means: 00000000 and 00000000 and 00000000. Each 8-bit is for a specific color.
1..8 is for and 9..16 for and 17..24 for
So in html #FF0000 means and here it is: 255;0;0
in html #00FF00 means which here is: 0;255;0
Does that make sense? what color you want combine it with these three 8-bit values.

这是颜色开关 \033[。见历史。

颜色代码如1;32（浅绿色）、0;34（蓝色）、1;34（浅蓝色）等。

我们用颜色开关\033[和0m无颜色代码终止颜色序列。就像在标记语言中打开和关闭选项卡一样。

    if ! [[ $color =~ '^[0-9]$' ]] ; then
       case $(echo $color | tr '[:upper:]' '[:lower:]') in

             -e "s/@green/$(tput setaf 2)/g" \
             -e "s/@yellow/$(tput setaf 3)/g" \
             -e "s/@blue/$(tput setaf 4)/g" \
             -e "s/@magenta/$(tput setaf 5)/g" \
             -e "s/@cyan/$(tput setaf 6)/g" \

为了可读性

如果您想提高代码的可读性，您可以echo先使用字符串，然后再添加颜色sed：

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

其他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精心安排的概述。维基百科文章“ANSI 转义码”对此非常有帮助。但是，由于颜色通常可以在每个终端中配置并且看起来不同，所以我更喜欢有一个可以在终端中调用的函数。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（排列方式受到 wiki 文章的启发）。例如，您可以将它们加载到您的 .bashrc/.zshrc 中，或者将它们作为脚本放在某处。

表情符号

答案中未提及的一件事是使用表情符号为输出着色！

echo : error message
echo : warning message
echo : ok status message
echo : action message
echo : Or anything you like and want to recognize immediately by color
echo : Or with a specific emoji

此方法非常有用，尤其是当您的脚本源编辑器支持显示 Unicode 时。然后您甚至可以在运行之前直接在源代码中看到彩色脚本！：

到目前为止，我最喜欢的答案是有色回声。

只是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/

您可以像使用 grep 一样使用它，例如，它会为每个参数使用不同的颜色为其标准输入着色

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

请注意，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

您绝对应该在原始 ANSI 控制序列上使用 tput。

因为有大量不同的终端控制语言，通常一个系统都有一个中间通信层。在数据库中查找当前检测到的终端类型的真实代码，然后您向 API 或（从 shell）向命令发出标准化请求。

这些命令之一是tput. tput接受一组称为能力名称的首字母缩略词和任何参数（如果合适），然后在 terminfo 数据库中查找检测到的终端的正确转义序列并打印正确的代码（希望终端能够理解）。

来自http://wiki.bash-hackers.org/scripting/terminalcodes

也就是说，我编写了一个名为bash-tint的小型辅助库，它在 tput 之上添加了另一层，使其更易于使用（恕我直言）：

例子： tint "white(Cyan(T)Magenta(I)Yellow(N)Black(T)) is bold(really) easy to use."
