Hi i want to merge a file with a particular key which is duplicate and also to sum up a particular field of all the duplicate key. also i need to take rest of the field from the first duplicate key record
Example : Key is first 5 bytes + 10 th bytes and i want to sum up the 8th field

Input file
11111 6789 1
11111 7898 1
11111 8787 1
22222 8787 2
22222 8788 2

O/p file
11111 678259 1
22222 87167 2

Your description and example are unclear.

What do you mean by "10th bytes" - what do you mean by "8th field"?

Please indicate which values you want to use as the keys (is it '11111' and '1' in the first three records and '22222' and '2' in the last 2 records). Please indicate which values you want to sum - I don't see how you got a total of 678259 from any of the values shown.

Is your input really as shown? Are there really blanks in between the fields?
You need to do a much better job of showing your example of input and output and explaining what you want to do.

Giving the starting position, length and format of each "field" would help.
