execution of a string being echoed in bash
hi all, I am trying to do a loop on a series of plotting function shown below:

Code:
colorlist=(blue red green); n=0;
for k in $xy; do
     psbasemap $range -JM$scale -B10g5 -X1 -Y1 -P -K > $outfile
     pscoast $range -JM$scale -B10g5 -D$res -P -W$lwidth -G$fill -O -K >> $outfile
     echo "psxy $k $range -JM$scale -B10g5 -Sc0.05 -P -G${colorlist[n++]} -O -K >> $outfile"
 done

I want to execute the command string being echoed and that for the last file to be executed within the list, it will omit the -K option. I need to run it like this sample code below:
Code:
psxy 1999.dat -R$range -JM$scale -P -M -Sc0.1 -Gblue -K -O >> $outfile
psxy 2000.dat -R$range -JM$scale -P -M -Sc0.1 -Gred -K -O >> $outfile
psxy 2001.dat -R$range -JM$scale -P -M -Sc0.1 -Ggreen -O >> $outfile

bunch of thanks!

glcolormask

GLCOLORMASK(3G) 														   GLCOLORMASK(3G)

NAME

       glColorMask - enable and disable writing of frame buffer color components

C SPECIFICATION

       void glColorMask( GLboolean red,
			 GLboolean green,
			 GLboolean blue,
			 GLboolean alpha )

PARAMETERS

       red, green, blue, alpha
			     Specify  whether  red, green, blue, and alpha can or cannot be written into the frame buffer.  The initial values are
			     all GL_TRUE, indicating that the color components can be written.

DESCRIPTION

       glColorMask specifies whether the individual color components in the frame buffer can or cannot be written.  If red is GL_FALSE, for  exam-
       ple, no change is made to the red component of any pixel in any of the color buffers, regardless of the drawing operation attempted.

       Changes to individual bits of components cannot be controlled.  Rather, changes are either enabled or disabled for entire color components.

ERRORS

       GL_INVALID_OPERATION is generated if glColorMask is executed between the execution of glBegin and the corresponding execution of glEnd.

ASSOCIATED GETS

       glGet with argument GL_COLOR_WRITEMASK
       glGet with argument GL_RGBA_MODE
