Hi bartus11,

Can you please explain what the above 'awk' is doing?

Thanks to all who replied to my question Smilie

It is just the perl code translated to AWK Smilie. It removes the second comma from beginning, and second comma from the end of the line if number of fields is equal 6.

Code:
# cat tst
EMPNO, ENAME, DESIGNATION, SALARY
10979, Arun Kumar, Cosultant, 35000
13555, Bidhu Shekar, Senior Consultant, 45000
15000, Kiran, Kumar, Senior, Consultant, 40000

Code:
# sed '$s/,//4;$s/,//2' tst
EMPNO, ENAME, DESIGNATION, SALARY
10979, Arun Kumar, Cosultant, 35000
13555, Bidhu Shekar, Senior Consultant, 45000
15000, Kiran Kumar, Senior Consultant, 40000

But in my opinion you should care about formatting the file directly at generation step (SQL?) since - according to the example provided, there are no deterministic rule(**) for identifying which of the coma is superfulous (all the more if you have big files with many different values in field $2 and $3 and that those fields may contains some additionnal unexpected comas.)

(**)Example:

Code:
32134, Tom, Billy, Joe, Corporation, 90909

Could as well be :

Code:
32134, Tom Billy, Joe Corporation, 90909
32134, Tom, Billy Joe Corporation, 90909
