awk help

Hi all,

I am using awk to get a string of numbers from a file:

cat file |awk '{print $2}'

this gives me several numbers:

25324
136753
234
1231214

how can I now use awk to add these figures together so I can get a total?

Thanks

lawrenzo,
one-line solution:
cat file | awk 'BEGIN{N=0};{N+=$2};END{print N}'

awk '{(s+=$2)} END {printf "%d\n",s}' your_file
