Another way might be

#!/bin/sh

# basename $filename .gz returns $filename unless it has a .gz
# suffix.
[ `basename $filename .gz` = $filename ] || {
	echo $filename has a .gz suffix
}

Intellectually, teachers fall between education theorists and bright
cocker spaniels. (Probably closer to the education theorists. The AKC has
been doing wonders with spaniels.) If you think I'm kidding look at the
GREs for education majors, whose scores are the lowest of all fields, and
remember that these are the smart ones. -- http://www.FredOnEverything.net
