Linux echo color settings

When Echo needs to change the color, use the-e parameter.
Format: ECHO-e "\ 033 [background color; font color M string \ 033 [0 m"
For example:
Echo-e "\ 033 [41; 36 m something here \ 033 [0 m"

The position 41 represents the background color, and the position 36 represents the color of the word.

Note:
1. The English "is used between the background color and the text color.
2. There is a m behind the text color
3. There can be no spaces before and after the string. If there is space, the output also has space.

The ASCII code is the beginning and end of the color call.
\ 033 [; M ...... \ 033 [0 m
Change the font to red and keep flashing
# Echo-e "\ 033 [31 m \ 33 [05 m please confirm whether to stop the current squid process, enter [Y/n] \ 033 [0 m"
Or

# Echo-e "\ 033 [31 m \ 033 [05 m please confirm whether to stop the current squid process, enter [Y/n] \ 033 [0 m"

The following are examples:

Echo-e "\ 033 [30 m black word \ 033 [0 m"

Echo-e "\ 033 [31 m red \ 033 [0 m"

Echo-e "\ 033 [32 m green word \ 033 [0 m"
