	Yes, there is an editor defined just for that purpose.  'sed' is
a stream editor, it reads the file one line at a time, does its thing, and
writes to a new file.  One problem, you must be able to define the lines
you want to delete using standard 'ed' commands.

	I believe you can also use fsplit to split the file into digestable
chunks.

	Try 'man sed' and 'man fsplit' if you have on line manuals.

	Every once and a while un*x does something right, like an editor
for files too big to edit.
