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

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
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'

  • Get http://xkcd.com/now image, inverts colors (I prefer dark backgrounds) and set it as wallpaper. You can replace the "convert" part by "wget -q http://imgs.xkcd.com/comics/now.png -O /tmp/now.png" if you prefer light backgrounds. The DISPLAY variable is here to work as a cron job. Show Sample Output

    convert http://imgs.xkcd.com/comics/now.png -negate /tmp/now.png ; DISPLAY=:0.0 awsetbg -c /tmp/now.png

  • Assuming you have zenity installed, and assuming that you keep your backgrounds in ~/backgrounds, then this should work for you! :)

    zenity --list --width 500 --height 500 --column 'Wallpapers' $(ls) | xargs xsetbg -center -smooth -fullscreen

  • I like the other three versions but one uses nested loops and another prints every color on a separate line. Both versions fail to reset colors before giving the prompt back. This version uses the column command to print a table so all the colors fit on one screen. It also resets colors back to normal before as a last step.

    for i in {0..255}; do echo -e "\e[38;05;${i}m${i}"; done | column -c 80 -s ' '; echo -e "\e[m"

  • Running this command turns shell tracing and shell verbose debugging on or off. Not only does it do that, it also uses your terminals builtin method of setting colors to make debugging much easier. It looks at the current shell options contained in the $- special bash variable and that lets this function set the opposite of the current value. So from the shell you could do a: setx; echo "y" | ( cat -t ) | echo "d"; setx and it will turn on debbuggin. This is an amazingly useful function that is perfect to add system-wide by adding it to /etc/profile or /etc/bashrc.. You can run it from the shell, and you can also use it in your shell scripts like my .bash_profile - http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html Show Sample Output

    function setx(){ sed '/[xv]/!Q2' <<< $- && { set +xv; export PS4=">>> "; } || { export PS4="`tput setaf 3`>>> `tput sgr0`"; set -xv; }; }

Just incase you ran this and it left your terminal in a funny place just type "reset" to return it to its original glory. This looks like there is much fun to be had. Thanks.
