Would something like this, base on a case statement work?
Code:
$ cat case_test
t1=Red
t2=Yellow
t3=Green
t4=Brown
t5=Blue
t6=Pink
t7=Black

case $1 in
 $t1) echo "The red ball is worth 1 point."         ;;
 $t2) echo "The yellow ball is worth 2 points."     ;;
 $t3) echo "The green ball is worth 3 points."      ;;
 $t4) echo "The brown ball is worth 4 points."      ;;
 $t5) echo "The blue ball is worth 5 points."       ;;
 $t6) echo "The pink ball is worth 6 points."       ;;
 $t7) echo "The black ball is worth 7 points."      ;;
 *)   echo "Any other option is a foul."            ;;
esac

I get the following simple sample output:-
Code:
$ ./case_test Yellow
The yellow ball is worth 2 points.
$ ./case_test White 
Any other option is a foul.
$

You could easily set the variables t1, t2, t3 etc. based on your tail output and set all the others to be dummy or the like to effectively switch off those tests.


Does that give you an angle?

billard-gl

BILLARD-GL(6)							   Games Manual 						     BILLARD-GL(6)

NAME

       billard-gl - OpenGL billiards game

SYNOPSIS

       billard-gl [options]

DESCRIPTION

       This  manual  page  documents  the billard-gl program. This manual page was written for Debian because the original program does not have a
       manual page.

       billard-gl implements a game of 8- or 9-ball billiards, which you can play against the computer or a friend.  The general idea of billiards
       is to hit the coloured balls with the cue ball in such a way that these balls fall in one of the six pockets of the table.

OPTIONS

       -f  -fullscreen
	      switches to fullscreen mode (can currently not be changed from inside billard-gl itself)

       -f  -windowed
	      switches to windowed mode (default; can currently not be changed from inside billard-gl itself)

       -t VALUE
	      texture size for the balls.  Valid values are 1 for full size textures, 2 for half size textures, 4 for quarter size textures, and 8
	      for eighth size textures.

       -tt VALUE
	      texture size for the table.  Valid values are 1 for full size textures, 2 for half size textures, 4 for quarter size textures, 8 for
	      eighth size textures, and 0 for no textures.

       -at VALUE
	      texture size for the display.  Valid values are 1 for full size textures and 2 for halfsized textures.

       -g VALUE
	      ball geometry; odd numbers >= 3.	Higher values create more complex geometry.

       To run billard-gl with minimum settings, try

	      billard-gl -t 8 -tt 0 -at 2 -g 3

       or for maximum settings, try

	      billard-gl -t 1 -tt 1 -at 1 -g 11

       All of the options are configurable from within billard-gl itself, unless stated otherwise.

       billard-gl was written by Stefan Disch, Tobias Nopper and Martina Welte.

       This  manual  page  was	written by Jamie Wilkinson <jaq@debian.org> and updated by Thierry Reding <thierry@doppeltgemoppelt.de> for Debian
