Hi vee_789,

With sort, based on the sample:
Code:
sort -t "$(/bin/echo ",")" -uk10,10 -k10Mr inputfile | sort -t "$(/bin/echo ",")" -uk5,5r
"200","0","","13011","-264","","","","13011","JUL","09"
"200","0","","13011","-263","","","","13011","AGO","09"

Regards

Hi vee_789,

What is the inputfile you are using?

With your last sample:
Code:
"200","0","","13011","-264","","","","13011","JUL","09"
"200","0","","13011","-264","","","","13011","JUL","09"
"200","0","","13011","-264","","","","13011","JUN","09"
"200","0","","13011","-263","","","","13011","JUL","09"
"200","0","","13011","-263","","","","13011","JUL","09"
"200","0","","13011","-263","","","","13011","AUG","09"

and using the code I posted before:
Code:
sort -t "$(/bin/echo ",")" -uk10,10 -k10Mr inputfile | sort -t "$(/bin/echo ",")" -uk5,5r

I get the output you said:
Code:
"200","0","","13011","-264","","","","13011","JUL","09"
"200","0","","13011","-263","","","","13011","AUG","09"


It's desirable a more representative sample to work with and.
