I tested my method and it works perfectly. I also modified it so that it takes an arbitrary range of line lengths, as well as allowing the user to decide whether to write to the file:
Did you test it with filenames containing IFS characters? Assuming a default IFS value, your option handling, sed invocations, and cat statement will all barf if a filename contains whitespace.

Greetings,
I want to use a script (preferably awk) which determines if the first character in a line is double-byte (as in Japanese or Chinese) and deletes it.
For example:

Hi All,
I have a very huge file (4GB) which has duplicate lines. I want to delete duplicate lines leaving unique lines. Sort, uniq, awk '!x++' are not working as its running out of buffer space.

hey guys,
I tried searching but most 'search and replace' questions are related to one liners.
Say I have a file to be replaced that has the following:

Hello,
I'm trying to figure out how to use sed or awk to delete single lines in a file. By single, I mean lines that are not touching any other lines (just one line with white space above and below).
Example:

doc::lua-oocairo-fontopt(3) Lua OO Cairo binding doc::lua-oocairo-fontopt(3)Name
lua-oocairo-fontopt - options controlling text rendering
Introduction
A font options object contains options that tell Cairo how to render text on surfaces. They can be created with the "font_options_create"
function in the main oocairo module (see lua-oocairo(3)), and retrieved from scaled fonts or context objects with "get_font_options"
methods.
Font options objects can be compared with the "==" operator. Two different objects with the same options set will be considered equal.
Methods
The following methods are available on font options objects:
opt:copy ()
Returns a new font options object, with identical options to opt. The two objects will be completely independent, so you can set them
to have different options.
opt:get_antialias ()
Get the current antialiasing mode, which will be one of the strings accepted by the "opt:set_antialias()" method.
opt:get_hint_metrics ()
Returns the current hint metrics option, which will be one of the same strings accepted by the "opt:set_hint_metrics()" method.
opt:get_hint_style ()
Get the kind of font hinting done when rendering text. Returns one of the strings accepted by the "opt:set_hint_style()" method.
opt:get_subpixel_order ()
Returns the current ordering of colour components in pixels used for subpixel rendering, which will be one of the same strings accepted
by the "opt:set_subpixel_order()" method.
opt:hash ()
Return a number which can be used as a hash key identifying the particular options in opt. That is, if you wanted to cache fonts
according to the options set on them, you could store them in a table with this hash value as the key. Two font options objects with
the same options will have the same hash value.
opt:merge (srcopt)
Add any options which are set to a non-default value in srcopt to opt if that still has the default value from them. The options in
srcopt will be unchanged. Nothing is returned.
opt:set_antialias (antialiastype)
Set the antialiasing mode used for drawing. The argument must be a string or boolean value accepted by the "set_antialias" method on
context objects (see lua-oocairo-context(3)).
opt:set_hint_metrics (hintmetrics)
Set the kind of hinting to be applied to the metrics, as opposed to outlines, of the glyphs in a font. The hintmetrics value must be
one of the following strings:
default
off
on
opt:set_hint_style (hintstyle)
Set the kind of font hinting done when rendering text. The hintstyle value must be one of the following strings:
default
none
slight
medium
full
opt:set_subpixel_order (order)
Used to inform Cairo of the arrangement of colour components in the pixels of a display device like a monitor. Only applies if
subpixel antialiasing is used. The order value must be one of the following strings:
default
rgb
bgr
vrgb
vbgr
The last two options refer to vertical arrangements of colours.
