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!

       -y y_lower
	      y_lower is a boolean value (0 or 1) indicating whether or not y-values (targets) should be scaled.  It defaults to 0.

       -s save_filename
	      save_filename indicates the filename to save the scaled data to.

       -r restore_filename
	      restore_filename indicates the filename reserved to hold the original (unscaled) data in case there is a need to restore.
