It's nice that you formatted the program's output to make it readable to <b>humans</b>... but it's a lot more useful if you make the output easy to integrate with other command line utilities.

For example, you may want to list only one resolution per line so that the result can be easily piped to grep. There are other things like this that you can do. Just some thoughts. Nice utility though.

I'd say if you are skilled enough to be writing shell scripts that pipe the output of one command to another, then I'd venture a guess that you are familiar enough with awk, sed, or even some perl one-liners to get just the resolutions. :-)
