What does the file look like? How big is it?
If it has 1 number per line, you could sort it in ascending order, and then take the first line (smallest) and last line (largest) .. i.e. (in ksh)
[tt]
SMALLEST=`sort myfile | head -1`
LARGEST=`sort myfile | tail -1`
[/tt]
You'll need to check the syntax of sort, but that's one possible way.

cat $file | awk '{printf ("%05d\n%05d\n%05d\n%05d\n%05d\n",$1,$2,$3,$4,$5);}' | sort
then do a head and tail on it ...
the %05d is digit (ie number) of 5 digits (minimum) with 0's preceding it if it is not 5 digits big ...
if you have numbers greater than 5 digits increase it, if you have number less than 5, then you can reduce it.
Hmm.
