Count of a column total

[teser]

How can i count the total value of a column. I want the total size of a several files that begin with b.

Example:
ls -l b*
-rw-r--r-- 1 smith agr 2501 Mar 7 10:43 bk131.sql
-rw-r--r-- 1 smith agr 2532 Mar 7 10:43 bk131a.sql

I need the total value of column 5 (2501 + 2532). Is there a command or simple script that can handle this?

This should do it ...

ls -l b*|awk '{s+=$5} END {print s}'

Post back if there are any problems.

Greg.

Teser,

it's easy with awk. Please, try this command:

ls -l b* | awk '{ sum += $5 } END { print sum }'

Bye!
