bash colors

For those of the terminal freaks, color is a bliss. But have you tried all the colors in the terminal. Today someone forwarded me a bash one liner for the same. Not sure where he got this from, anyway here is the one liner for you all:

for c in `seq 0 255`;do t=5;[[ $c -lt 108 ]]&&t=0;for i in `seq $t 5`;do echo -e \”e[0;48;$i;${c}m|| $i:$c `seq -s+0 $(($COLUMNS/2))|tr -d \'[0-9]\’`e[0m\”;done;done
