Thanks Jean-Pierre for the reply.

To understand the requirement, All the columns in the test.txt are independent and no relation between. in other words, it is source file.

the output derived from the file should be

TGT_COL1 TGT_COL2 TGT_COL3
1 500 500
2 290 290
3 100 100

ie: TGT_COL2 = sum of SRC_COL2 / unique count of SRC_COL1
TGT_COL3= sum of SRC_COL4 / unique count of SRC_COL2


PS : I have updated the test.txt in the subject post.

Thanks

NAME
sum - calculate a checksum for a file SYNOPSIS
/usr/ucb/sum file... DESCRIPTION
sum calculates and displays a 16-bit checksum for the named file and displays the size of the file in kilobytes. It is typically used to look for bad spots, or to validate a file communicated over some transmission line. The checksum is calculated by an algorithm which may yield different results on machines with 16-bit ints and machines with 32-bit ints, so it cannot always be used to validate that a file has been transferred between machines with different-sized ints. USAGE
See largefile(5) for the description of the behavior of sum when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes). ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWscpu | +-----------------------------+-----------------------------+ SEE ALSO
sum(1), wc(1), attributes(5), largefile(5) DIAGNOSTICS
Read error is indistinguishable from EOF on most devices; check the block count. NOTES
sum and /usr/bin/sum (see sum(1)) return different checksums. This utility is obsolete. SunOS 5.11 8 Nov 1995 sum(1B)
