Keywords: vi lines search

|1) Two (or more) blank lines, one after the other.
|
|2) A line longer than "n" characters.
|
|(For the former, I've tried various combinations of ^$ and
|Ctrl-V-Return, but none have worked. For the latter, I would suppose
|that "/^(81 dots)$" would find lines over 80 characters long, but
|that is hardly practical. I would expect there to be a more elegant
|solution... :-)

This looks like a job for... Superchicken, er, awk.

vi:
(1) vi can't match across lines, so no joy.
(2) There is no counted form of the * operator.

awk:
(1) Have a variable remember previous line was blank.
(2) See builtin 'length'.

You may also want to print out the line number for use later.
