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!

SYNOPSIS

       ppmdither [-dim power] [-red shades] [-green shades] [-blue shades] [ppmfile]

DESCRIPTION

       Reads  a  portable  pixmap as input, and applies dithering to it to reduce the number of colors used down to the specified number of shades

       format suitable for color printers, use -red 2 -green 2 -blue 2.

OPTIONS

       -dim power    The  size of the dithering matrix.  The dithering matrix is a square whose dimension is a power of 2.  power is that power of
		     2.  The default is 4, for a 16 by 16 matrix.

       -red shades   The number of red shades to be used, including black; minimum of 2.

       -green shades The number of green shades to be used, including black; minimum of 2.
