Shell Programming and Scripting

Not sure I understand the requirement fully, perhaps you can adapt this...

Code:

awk '
  $1 == "Date" {
     d = $3 " " $4 " " $5
     next
  }
  $1 == "object" {
     next
  }
  {
    print d, $0
  }
  ' file1 | sort -u -k4,5

...which gives...

Code:

October 30 10:22:56 Ananya 157677 102 Oct 18 14:34
October 30 10:22:56 Chhavi 157682 107 Oct 18 14:34

Where priya had reference as 157676 at 10:22:56 but changed to 145020 at
10:23:56 and 145687 at 10:24:56 .
similarly for Pakash and Chhavi . However ,
there exists no other entry for ANY OBJECT whose ANY parameter has not changed.

I hope now the things are clear . unix forum has always given me desired answer of my queries hoping for the same
