As I have already said,

    grep -whor '[A-Z][A-Za-z]*Exception' * | sort | uniq -c
for a histogram of exceptions inside logs downloaded from a bunch of nodes.

As for -w, my favourite case is https://unix.stackexchange.com/questions/110645/select-lines...

As for -o,

    grep -o ........-....-....-....-............
It may look like Morse code, but what it does is greps UUIDs out.

cool stuff, i was messing around with this. To then take that list of exceptions and find them back the actual files again, tack on at the end: `| grep -Fwf - *`
