multiple operation
Fellows I ran in to a problem this morning and could not figure out a solution to it.
I have a file like

OBJECT="ABC" GFT="JHU"
DESCRIPTION="ABC MNCL JHDG "
OBJECT="ABC" GFT="JHU"
DESCRIPTION="ABC MNCL JHDG "
OBJECT="ABC" GFT="JHU"
DESCRIPTION="ABC MNCL JHDG "
DESCRIPTION="ABC MNCL JHDG "
DESCRIPTION="ABC MNCL JHDG "
OBJECT="ABC" GFT="JHU"
DESCRIPTION="ABC MNCL JHDG "


What I am trying to do is whenever there is a repition of pattern DESCRIPTION consecutively I want to delete all the lines but first.
On the outpur file i want to add consecutive lines to one line.

I couldn't figure out a way to do the first step.
But for secod i was trying this script

#! /bin/sh
awk 'BEGIN {
RS="";
FS="\n";
}
{ print $1 $2 }' filename

give the output record too long

Any thought why is it doing it more over Can i use paste command to do the second step??
