Re: easy way to add a bunch of numbers in a script

I like doing it this way:

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

or in a stream by

         Sum=`generate stream | awk '{sum+=$1} END{print sum}'`

for example to get the size of all file in a directory that begin with the
letter a:

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

Hope this helps,
