anyone know of a way to customize the coloriing of a bash screen?

I'm looking to have the screen do the following:

Anytime any program outputs a line containing the word 'error' or 'warning' I want that whole line to turn red or blue. I use a suite of third party tools that print out a stream of info messages (one per line) and the errors and warning info messages tend to get lost, since there is a really large amount of data being pushed to the screen.

Being able to add more colorings based on a regex matching would be awesome.

There's log watchers that can do that. I forgot the name but I'm sure loganalysis.org, Freshmeat, Sourceforge, Savannah or Berlios could show some.

here's a little script I found online that's nicer than the one I created for myself.

Code:

#!/bin/bash
#
#   This file echoes a bunch of color codes to the 
#   terminal to demonstrate what's available.  Each 
#   line is the color code of one forground color,
#   out of 17 (default + 16 escapes), followed by a 
#   test use of that color on all nine background 
#   colors (default + 8 escapes).
#

T='gYw'   # The test text

echo -e "\n                 40m     41m     42m     43m\
     44m     45m     46m     47m";

for FGs in '    m' '   1m' '  30m' '1;30m' '  31m' '1;31m' '  32m' \
           '1;32m' '  33m' '1;33m' '  34m' '1;34m' '  35m' '1;35m' \
           '  36m' '1;36m' '  37m' '1;37m';
  do FG=${FGs// /}
  echo -en " $FGs \033[$FG  $T  "
  for BG in 40m 41m 42m 43m 44m 45m 46m 47m;
    do echo -en "$EINS \033[$FG\033[$BG  $T  \033[0m";
  done
  echo;
done
echo

Just remember to use "echo -e" when you finally find the color code(s) you want. I'm guessing this is what you're after:

echo -e "\e[1;37m\e[41mhello\e[m"

I was hoping someone could point me to one or two script, or suggest search words. I keep getting scripts that do not allow the coloring of arbitrary program output. (Or they suck at handling sig terms)
