this

  convert  -draw "line 10,10,20,20"  text.jpg out.jpg

draws a line on the image from 10,10 to 20,20 

so does this:

  g="line 10,10,20,20"
  convert -draw "$g"  text.jpg out.jpg

but this chokes:

  g='-draw "line 10,10,20,20"'
  echo $g
  convert $g text.jpg out.jpg

appearantly convert is seeing "line 10,10,20,20" as two 
arguments, divided at the space.

I'm at a loss. any ideas? 

Mike
