Hi,
In a shell, Bourne in my case, what tools would I use, can how would I
use them to add up a set of numbers in a file.
For example if I had a file holding...

filename
------------
10
15
7
2

How would I derive the total of those numbers, 34?

Any help what-so-ever appreciated.

Thanks
Adam.

See my answer in comp.unix.questions. (The first solution is POSIX
rather than Bourne.)

There are many ways to do this - here is a pretty short/easy one:

awk '{sum += $1} END {print sum}' file
