With
printf, you can colour the message:
Code:
printf "\x1b[33mTest Message\x1b[0m\n"
will write
Test Message
you can also make the message blink, bold, italic, and bg/fg colours.
here are the codes I know (replace 33 in the example with the code):
1 bold
4 underline
5 blink
7 bg/fg inverted
30-37 colours
40-47 bg colours
they can also be combined in th form x;y or x;y;z
