| In the Linux system, the shell command can efficiently run concurrent processing tasks, and the shell script is not boring. There are not only magic sounds but also the color display of the shell. Next, we will use the colors in the shell to improve the quality of the shell script in seconds. |
Let's take an example:
echo -e"\033[44;37;5m ME \033[0m COOL"
The above command sets the background to blue, the foreground to white, blinks the cursor, and outputs the character "ME", then resets the screen to the default setting and outputs the character "COOL". "e" is an optional option of the command echo, which is used to activate the parser for special characters. "\033" leads an unconventional character sequence. "m" means to set the property and end the sequence of unconventional characters, the real valid characters in this example are "44;37;5" and "0". Modifying "44;37;5" can generate a combination of different colors, and the numerical value has nothing to do with the sequence of coding.
