Help on a simple awk prob

[jmiles]

I have to take a file with the format:
97865467
3
10
3
5
7
9
93689383
6
6
10
8
2
4
99836353
ect...

where the 8 didgit numberis an id number and the six numbers (on the six lines) following, are marks.

and with this file i must add up the six marks and put them next to the id number for each person so i edn up with a file looking like this:

99823634 34
99383635 50
ect...

any help on how i would go about this would be greatly appreciated

thanking you!

Hello, JMiles!

Please, try awk this script:


length($0) == 8 {

# print previous id and sum but not if is first row
if (NR != 1)
print id, sum

id = $0
sum = 0

}


length($0) < 8 { sum += $0 }


Awk is good choice for this problem.

Tell me, does is works.

Bye!
