- Report:
- Output of colors under Linux terminal
- You can also create colorful fonts and patterns at the command line, just add some color codes
- Example 1:
- printf ("\033[44;31m sunrier\033[0m")
- Where 44 represents the background color, 31 represents the font colour, Sunrier is a string, and the following \033[0m is the control code, which indicates that all properties are closed, m means that the property is set and then ends
- Example 2:
- Echo-e "\033[41;36m Red Bottom Green character \033[0m"
- Where 41 represents the background color and 36 represents the font
- Word Background color range: 47----
- 40: Black
- 41: Crimson
- 42: Green
- 43: Yellow
- 44: Blue
- 45: Purple
- 46: Dark Green
- 47: White
- Word Color: 37-----------
- 30: Black
- 31: Red
- 32: Green
- 33: Yellow
- 34: Blue
- 35: Purple
- 36: Dark Green
- 37: White
- Description of the ANSI control code
- \33[0m Close all properties, set as default properties
- \33[1m Setting High brightness
- \33[4m Underline
- \33[5m Flashing
- \33[7M Reverse Display
- \33[8m blanking
- \33[30m--\33[37m setting foreground color
- \33[40m--\33[47m Set background color
- \33[na the cursor to move n rows
- \33[NB cursor down n rows
- \33[NC cursor right shifts n rows
- \33[nd cursor left n rows
- \33[Y;XH Setting the cursor position
- \33[2J Clear Screen
- \33[k clears the contents from the cursor to the end of the line
- \33[s Save Cursor position
- \33[u Restore cursor Position
- \33[?25l Hide Cursor
- \33[?25h Display cursor
- Generally used to write \33 \033, where \nnn insert nnn (note N is 1 to 3 bits) (octal) represents the ASCII character
