Control code under Ubuntu:
The commonly used ANSI control codes are as follows (some are not supported):
\033[0m close all properties
\033[1m highlight
\033[2m brightness halved
\033[3m Italic
\033[4m underscore
\033[5m flashing
\033[6m flash
\033[7m reverse display
\033[8m blanking
\033[9m A horizontal line in the middle
10-19 About fonts
21-29 is basically the opposite of 1-9
30-37 Set the foreground color
40-47 set background color
30: black
31: red
32: green
33: yellow
34: blue
35: purple
36: dark green
37: white
38 Turn on underline and set the default foreground color
39 Turn off underline and set the default foreground color
40 black background
41 red background
42 green background
43 brown background
44 blue background
45 Magenta Background
46 Peacock Blue Background
47 white background
48 Don't know something
49 Set the default background color
50-89 useless
90-109 sets the foreground and background again, which is lighter than the previous color
\033[nA Move the cursor up n lines
\033[nB Move the cursor down n lines
\033[nC Move the cursor right n lines
\033[nD Move the cursor to the left by n lines
\033[y;xH set cursor position
\033[2J Clear screen
\033[K Clear the content from the cursor to the end of the line
\033[s save the cursor position
\033[u restore cursor position
\033[?25l hide the cursor
\033[?25h display cursor

Save the code as chcolor.cpp file.
Compile
g++ -std=c++11 -o chcolor chcolor.cpp
Copy chcolor to the /bin/ directory: sudo cp chcolor /bin/
use
Switch to root: sudo su
Enter in the terminal: chcolor -h
输入：chcolor -s underline -bg blue -fg yellow
You can set the style, background color, and foreground color at the same time:
cout << "\033[1;31;45mHello, ubuntu!\n";
//中间用;进行分隔There is a question: if it is not used under the root user, there will be no effect, please expert guidance, thank you!
