First of all, I know this can be more eassily done with perl or other scripting languages but, that's not the issue. I need this in sed. (or wander if it's possible )

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:

Hi all,
I'm looking for a way (sed or awk) to delete multiple lines between blank lines containing two patterns ex:

merge
MERGE(1) General Commands Manual MERGE(1)NAME
merge - three-way file merge
SYNOPSIS
merge [ options ] file1 file2 file3
DESCRIPTION
merge incorporates all changes that lead from file2 to file3 into file1. The result ordinarily goes into file1. merge is useful for com-
bining separate changes to an original. Suppose file2 is the original, and both file1 and file3 are modifications of file2. Then merge
combines both changes.
A conflict occurs if both file1 and file3 have changes in a common segment of lines. If a conflict is found, merge normally outputs a
warning and brackets the conflict with <<<<<<< and >>>>>>> lines. A typical conflict will look like this:
<<<<<<< file A
lines in file A
=======
lines in file B
>>>>>>> file B
If there are conflicts, the user should edit the result and delete one of the alternatives.
OPTIONS -A Output conflicts using the -A style of diff3(1), if supported by diff3. This merges all changes leading from file2 to file3 into
file1, and generates the most verbose output.
-E, -e These options specify conflict styles that generate less information than -A. See diff3(1) for details. The default is -E. With
-e, merge does not warn about conflicts.
-L label
This option may be given up to three times, and specifies labels to be used in place of the corresponding file names in conflict
reports. That is, merge -L x -L y -L z a b c generates output that looks like it came from files x, y and z instead of from files
a, b and c.
-p Send results to standard output instead of overwriting file1.
-q Quiet; do not warn about conflicts.
-V Print RCS's version number.
DIAGNOSTICS
Exit status is 0 for no conflicts, 1 for some conflicts, 2 for trouble.

BUGS
It normally does not make sense to merge binary files as if they were text, but merge tries to do it anyway.
