I assume that you know that sed is not a common tool for this project, and, as you said, bash isn't well known for handling floating point values. If you want to process your file entirely in shell code, ksh would be a good choice. Otherwise, as you well know, awk is perfectly suited to problems like this.

What have you tried to solve this on your own? Where are you stuck?
Sorry, I was in a pretty bad accident last night and I just got back from the Hospital. I probably won't be able to respond more completely until tomorrow. I will answer your questions in my next post.

Thanks,

       ager.  It uses any 64x64 pixmap as a background.

       dash.  A summary of options is included below.

       -B PIXMAP, --background=PIXMAP
	      Use the given pixmap as the clock background (size must be 64x64).

	      Draw the hands (hour, minute and second) in the specified color.

       -S COLOR, --second-hand-color
