You can use these ANSI escape codes :

(您可以使用以下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

And then use them like this in your script:

(然后在脚本中像这样使用它们：)

#    .---------- constant part!
#    vvvv vvvv-- the code from above
RED='33[0;31m'
NC='33[0m' # No Color
printf "I ${RED}love${NC} Stack Overflow
"

which prints love in red.

(用红色印出love 。)

From @james-lim's comment, if you are using the echo command, be sure to use the -e flag to allow backslash escapes .

(根据@ james-lim的注释， 如果使用的是echo命令，请确保使用-e标志以允许反斜杠转义 。)

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

(don't add "\n" when using echo unless you want to add additional empty line)

(（除非要添加其他空行，否则在使用echo时请勿添加"\n" ）)
