Linux shell script output with color text

Linux shell script output with color text

The color of the text terminal can be generated by using the ANSI unconventional character sequence.

Example: "Echo-e \033[44;37;5m BLUE \033[0m"

"Echo-e \033[44;37;5m BLUE \033[0m BLACK"

The area that needs to be modified is the red underlined part, where [the contents of the ***m section are replaced by the following number, and the content that you want to paint is later.

The above command set the function as follows: The background color is blue, the foreground color is white, the font blinks, the output character "blue", and then reset the screen to the default settings, the output character "BLACK". "E" is an optional option for the command echo, which is used to activate the parser for special characters. "\033" guides the non-regular character sequence. "M" means to set the property and then end the unconventional character sequence, the real valid characters in this example are "44;37;5" and "0". modifying "44;37;5" can produce combinations of different colors, which are not related to the sequence of values and encodings.

The encoding you can choose is as follows:

"The foreground is the font color;

The background is similar to the shading of the text, or it is called the back color. 】
