Hi there,

I have a logfile which has the following layout:

20080812 0 20
20080812 12 10
20080812 12 10
20080812 12 10

I want to sum the "12" on the last 3 lines and save the "20" on the first line. The final output should be

20080812 36 20

I think that should me more easier with awk ? Many thanks in advice.
