[Orca-users] Howto use perl expr to sum data ?

[mian at vip.cybercity.dk]

Hello All

I have data in multiple columns, that I would like to sum up to make one 
total graph.

My column_name is of the form bptm#1_total_bytes_sec, bptm#2_total_bytes_sec 
and so on.

On some systems number of bptm's can vary from 0 to 48, so it would very 
helpfull to could make a generic config-file.

Regards
Michael
