Change the color

Hello,

Excuse me for these basic questions that I made, but I want to ask something more:
In my script, appears to the user, the sentence: Wait a little.

This sentence appears in black color… How I can the color on sentence? Which is the command in script?

Assuming you have a standard terminal (e.g. gnome-terminal) and you're writing a script in /bin/bash (please, can you clarify?) a method can be:

Code:

tput setaf 1

echo Hello world\!

tput setaf 0

this should print the string "Hello world!" in red. By this method you have 8 basic colors available, numbered from 0 (black) to 7. The setaf string in the above commands stats for "set ANSI foreground". See man tput and man terminfo for details. The latter contains a list of available colors (see section "Colors").
