Hi,

I would like to use ANSI colour sequences when showing a prompt using
read -ep but I can't figure out how to do this. Is this possible? Am I
missing something? Using standard escape sequences does not appear to
work, my current test code looks like:

read -ep "\033[1mABC\033[0m" value;

Using echo -e the output is bold as expected:

echo -e "\033[1mABC\033[0m";

I cannot see any option in `bash help read` that affects ANSI escape
sequences. I suspect escaping is different in this instance, but my
experiments have not yielded anything so far. Any pointers much
appreciated!

check out https://github.com/dethrophes/Experimental-Bash-Module-System/blob/master/bash/ConsoleFuncs.sh

it solves your problems in 2 ways
it creates variables with the color escape sequences.
2 options using tput or using the ansi escape sequences directly.

read -ep "\033[1mABC\033[0m" value;

read -p "${ATTRIB_Bold}ABC${NO_COLOUR}" value;

This version is bash secific but I should have some more generice code lying around if that is an issue.

cheers
John
