Does anyone know of a utility which will extract the nth line of a
file?
/* End of text from uiucdcsb:comp.unix.questions */

head -n file | tail +m

will isolate lines m-n from file.

Example:
------------------------------------------------------------------------
% cat foo
this
is
a
test
of
extracting
lines
% head -4 foo | tail +3
a
test
------------------------------------------------------------------------
