Screaming Penguin - Source Does Matter

Another short oneliner to count hits per day (just to teach some unix basics :)

maybe for your date format you'll have to tweak it but you
get the idea. with awk it would be easier of course.

tv:/var/log/httpd # grep "GET /default.ida?XXX" access.log |cut -f1,4 -d' '|cut -f1,2 -d'/'|sort -mb -t' '|uniq -c -f1

This curve persuaded me to turn it off a few days (25/Aug).
The IP is the first hit per day. only the number (count/day) is interesting.
