i like your fighting attitude till the problem gets solved.

Previously it was taking 35 mins and now it is taking 0.9 secs
I should say at least 10 Thanks but there is no such button on forum...

I agree. Don's patience is extraordinary. I'm tempted to let the enterprise reap what they've sown.

FWIW, an adaptation to my previous script...
Code:
nawk '$6!=m{m=$6; c=0} {if($7!=p) {A[++c]=$0; if(c>2)print A[c-n]} else A[c]=A[c] ORS $0} {p=$7}' n=2

Mind you, parsing ls output like this may not be reliable, since ls may change format if the file is less than 6 months old..
In the POSIX locale, at least $6 and $7 are stable, so it may be best to use:
Code:
LANG=C ls -ltr
