Unbelievable Shell Colors, Shading, Backgrounds, Effects for Non-X

I've been using linux for almost a decade and only recently discovered that most terminals like putty, xterm, xfree86, vt100, etc., support hundreds of shades of colors, backgrounds and text/terminal effects.

This simply prints out a ton of them, the output is pretty amazing.

If you use non-x terminals all the time like I do, it can really be helpful to know how to tweak colors and terminal capabilities. Like:

echo $'\33[H\33[2J'

Adding Color Escape Codes to global CC array for use by echo -e

I was looking for the fastest way to create a bunch of ansi escapes for use in echo -e commands throughout a lot of my shell scripts. This is what I came up with, and I actually stick that loop command in a function and then just call that at the beginning of my scripts to not clutter the environment with these escape codes, which can wreck havok on my terminal when I'm dumping the environment. More of a cool way to store escape ansi codes in an array. You can echo them like:

echo -e "${CC[15]}This text is black on bright green background."

I usually just use with a function:

# setup_colors - Adds colors to array CC for global use

# 30 - Black, 31 - Red, 32 - Green, 33 - Yellow, 34 - Blue, 35 - Magenta, 36 - Blue/Green, 37 - White, 30/42 - Black on Green    '30\;42'

function setup_colors(){ declare -ax CC; for i in `seq 0 7`;do ii=$(($i+7));CC[$i]="\033[1;3${i}m";CC[$ii]="\033[0;3${i}m";done;CC[15]="\033[30;42m"; export R='\033[0;00m';export X="\033[1;37m"; };

export -f setup_colors

CC[15] has a background of bright green which is why it is separate. R resets everything, and X is my default font of bright white.

CC[15]="\033[30;42m"; R=$'\033[0;00m'; X=$'\033[1;37m'

Those are just my favorite colors that I often use in my scripts. You can test which colors by running

for i in $(seq 0 $((${#CC[@]} - 1))); do echo -e "${CC[$i]}[$i]\n$R"; done
