parse a log file and remember last line
Hi all:

I'm working on a HPUX 11.23 system and I am needing to parse a tomcat-jakarta log file for memory use. Getting the desired data is easy, assuming the log file does not grow. This file grows constantly and I want to check it q 5 min. The next check will pick up from where it left off 5 min ago and read only the new entries looking for the desired pattern. So, read and parse the desired data from the log file, 5 minutes later read the newer entries and parse the desired data. Needs to be a shell (ksh) script so I can pass it off to the users and let them maintain it.

I have seen lots of entries for log analysis and parsing but nothing is really fitting my needs - or I am missing something.

Many thanks
