A wise man once analysed this problem:

#!/bin/sh
egrep -v '\.(gif|GIF|jpg|JPG|css|CSS) HTTP|^192\.(9|18|29)\.' inf >e

#!/bin/sh
gawk '!/\.(gif|GIF|jpg|JPG|css|CSS) HTTP|^192\.(9|18|29)\./{print}' inf >a

#!/bin/sh
perl -ne'/^192\.(?:9|18|29)\./||/\.(?:gif|GIF|jpg|JPG|css|CSS) HTTP/ or
print' inf >p

Apart from being 100 times shorter than the given Java solution, all
three solutions are *much* faster (alas, egrep beat Perl for both golf
and speed on this one). But hey, the Java web site *still* claims that
Java beat Perl on this problem, so that must be right. ;-)
