in thread bootlog.txt shrinker

Thanks... I'm looking into your code now: there's a lot I don't understand in there (like the indexing by key) but I'll have a good look.

I could probably have just searched for lines containing FAIL (any case) but wasn't sure if that'd fail to report some other errors.

    Nothing special, its just a way to speed up searches when you have well defined search keys. You can do:
    $search_for = 'Failed|Ugly|Broken'; while (<LOG>) { print if /$search_for/; ...
    if you don't have a whole lot of items (or so I look at it, probably benchmarkably wrong) but if you've got a larger number, using a hash is a nice way to speed it up over the iterate through an array approach you used. It needs to be something like this, where the looked for text is consistent, though.

    The only other sneakiness (besides lopping of the initial memory (?) hex in brackets part to make the split-ing easier) was to see that there were 2 kinds of data lines; one w/ an = and variable left-hand side words and one w/o the = and the last word always being the 'result'.

    'course I wrote the mess before recognizing that you were printing unless the data matched a list item.
