Hi there,

I have an application runnig on HP_UX which logs critical mesages to a log file.

What I would like to do is tail the log file and report on new messages. Easy....I here you say.

The log file is continuing to be written to and the check scritp will be executed from cron. I was thinking on having a file with the last wc -l stored in it and then having a variable that is the current wc -l of the log file.

How could I subtract the original wc from the stored wc to use in the tail -x? these would be only the new messages.

(orig wc) - (new wc) = tail -n lines

Do you know what I mean? From these new lines I will report and audit..

Cheers in advance all you lucky people.
