Thank you for the suggestions.
My original intent was to avoid script programming as much as possible
and yet gain reasonably good summary.
I guess the time is over for a simple shell scripting to
produce a meaningful summary from ever evolving log record.
(Yes, my script goes over the log many times and in that sense it is not
very efficient, but
it can handle 100+MiB |mach mochitest-plain| of debug build of FF in several
seconds on my local PC and not too bad for my purpose of obtaining a
meaningful summary without investing too much in programming.)
When I have a time to re-engineer my script, I will post a prototype for
review by people who may be interested in such a script.
TIA
