Thanks for replying so quickly and providing me the desired solution.
I tried the solution provided by RudiC and Sathyaonunix. Both are providing me the solutions. I am looking into the script by Pamu ( I am finding it difficult to understand as my expertise in Unix is not good, so kindly give me some time.)
As regarding query raised by RudiC
(i) if the third column entries are identical, then only one row is to be retained in the original file.
(ii) values cannot be negative.
(iii) the lines without duplicate values to be retained in the orginal file as such.
Thank you once again.
Manoj
Thanks for providing above details.
As per your current requirement I've modified script lit bit.
Now please check.
A[$1,$2]++ # Increments the array index for $1 and $2.
B[$1,$2]=B[$1,$2]?B[$1,$2]<$3?$3:B[$1,$2]:$3 # Here we compare is $3 is greater than previous $3 for $1 and $2 and retain max value and assign it to B[$1,$2]

In a table, date is stored in a column as "2011-01-4".
