In Linux, shell scripts output color text

The color of the text terminal can be generated using an ANSI unconventional character sequence. Example:

 

Echo-e "/033 [44; 37; 5 m me/033 [0 m Cool"

 

The preceding command sets the background color to blue, the foreground color to white, the font to flash, the output character "me", and then reset the screen to the default settings, the output character "cool ". "E" is an option for the echo command, which is used to activate the parser for special characters. "/033" leads the sequence of unconventional characters. "M" means setting the attribute and ending the unconventional Character Sequence. In this example, the valid characters are "44; 37; 5" and "0 ". Modify "44; 37; 5" to generate a combination of different colors. The values are irrelevant to the order of encoding.

 

The optional encoding is as follows:
