	Well, these may not be the most efficient ways, but they should
work:

	(Assuming we are working with "bigfile", which is 99999 lines long)

	% head -99989 bigfile > bigfile2

	(The above command makes a copy of bigfile, minus the last 10 lines)

	% tail +10 bigfile > bigfile3

	(The above command makes a copy of bigfile, minus the first 10 lines)
