I was curious about just adding colour to echos that I do in scripts and here is how:
echo -e "This is red->e[00;31mREDe[00m"
I havent found out how the colours actually work (eg tables of colours) but if you experiment with the numbers you can come up with different foreground and background colours.
UPDATE:
Ok here is a script to dump out the various colour combos.
#/bin/sh
# Show all the colors of the rainbow, should be run under bash
for STYLE in 0 1 2 3 4 5 6 7; do
for FG in 30 31 32 33 34 35 36 37; do
for BG in 40 41 42 43 44 45 46 47; do
