Sum of some data (easy points ...)

[Olivier Decorse]

Hi,
i'm searching how to do the sum of data in a file.
For example, file contains :
15 a
15 b
30 c
I want to do :
cat file | awk '{print $1 }' | unix_command_that_do_a_sum
and receive :
60

Thank's in advance.

# perl -nle'END{print$sum}$sum+=$_' file

Enjoy, Have FUN! H.Merijn
