Hello all,
Need to pick your brains,
I have a 10Gb file where each row is a name, I am expecting about 50 names in total. So there are a lot of repetitions in clusters.
So I want to do a
sort -u file
Will it be considerably faster or slower to use a uniq before piping it to sort... (3 Replies)

mlm
FBB::mlm(3bobcat) OFoldStream manipulator FBB::mlm(3bobcat)NAME
FBB::mlm - Manipulator modifying left margins of OFoldStream objects
SYNOPSIS
#include <bobcat/ofoldstream> or
#include <bobcat/ofoldstreambuf>
Linking option: -lbobcat
DESCRIPTION
The mlm class implements a manipulator that can be inserted into OFoldStream objects to modify the stream's left margin by a requested
amount. The request cannot result in a negative left margin value. If a negative left margin would be the arithmetic result of the request
then left margin 0 will silently be used.
Depending on the tab-setting of the OFoldStream the inserted value represents the number of blank space characters or the number of
tab-characters that will be added to the left margin.
The request will be processed at the next newline character or std::flush or std::endl manipulator that is inserted into the stream. If a
line is still empty once an mlm object and a flush manipulator are inserted into the stream then the new left margin will be effective at
the next word inserted into that line (cf., the example section below)
A bad_cast exception is thrown when the manipulator is inserted into an ostream that is not using a OFoldStreambuf buffer.
