RGB Command Challenge

Create a command that takes three arguments for red, green, and blue that are numbers between 0 and 255. Combine the numbers into a vt100 (ANSI) RGB color escape and print the escape sequence invisibly coloring anything printed after. Test by printing different things in different colors. Once that works go back and assign random default color values for each if less than three arguments are passed.

Requirements

• Must include a safe shebang line if a script.
• Use raw escape sequences.
• Do not use tput in any form.
• When using echo do not use -e.
• When ./rgb then print random color

Hints

• Research printing in color on the terminal
• You will need to escape escape (didn’t stutter).
• Research how to generate a random number in your language.

Bonus

• Validate using language test framework.
• Check that each value is between 0 and 255 or print usage.
• Write a for loop to cycle through gradient output to the terminal.
