Well, here's a couple:

	cat -n $file

	pr -n -t $file  (You missed pr :-)

	awk '{ print NR, $0}' $file

These all assume you want them numbered in decimal.

To number in hex and octal use:

	awk '{ printf("%x %s\n", NR, $0) }' $file		# Hex
	awk '{ printf("%o %s\n", NR, $0) }' $file		# Octal

Some system's don't support "cat -n".  (I think SYSVR3 ??)  The awk solution
should work most anywhere.

Have fun!
