Read Command : Display the prompt in color (or enable interpretation of backslash escapes)

Question

I often use something like read -e -p \"> All good ? (y/n)\" -n 1 confirm; to ask a confirm to the user.

I\'m looking for a way to colorize the outpu

Answer 1

Break your query into two components:

1. use echo -e -n to display the prompt
2. collect the user response with read

e.g:

echo -e -n "\e[0;31mAll good (y/n)? "   # Display prompt in red
echo -e -n '\e[0;0m'                    # Turn off coloured output
read                                    # Collect the user input

The echo -n option suppresses the trailing newline.
