How to change the output color of echo in Linux?

Question

I am trying to print a text in the terminal using echo command. I want to print the text in a red color. How can I do that?

Answer 1

echo -e "\033[31mYOUR TEXT\033[0m"

1. The -e argument causes echo to interpret the back-slash character in a special way.
2. When back-slash interpretation is enabled, "\033" is a representation for the 'escape' character.
3. The terminal recognizes many special "escape sequences" that start with the escape character.
4. The escape sequence "\033[31m" turns the text color to red.
5. The escape sequence "\033[0m" at the end resets the color back to the default.
6. A lot more information on these escape sequences can be found at https://en.wikipedia.org/wiki/ANSI_escape_code
