Shell Programming and Scripting

Code:

sed -n '/robots.txt/!{s/\([0-9]\{1,\}\.[0-9]*\.[0-9]*\.[0-9]*\).*\/\(.*\.txt\).*/\1 \2/p;}'  myaapache.log

Above command will search all txt except robots.txt from apache logs and show like

Code:

94.136.63.119 idsuper.txt
174.121.67.233 fx29id1.txt

I want to block that ip address automatically, i need script that will check all *.txts from apache log but ignore robots.txt whenever such hit come that will pick ip address from log and block ip address like

Code:

iptables -I INPUT -s ip-address -j DROP

script will run after every two minute and check only update apache log not complete apache log file.

Apache have a date format like this -> 01/Jun/2010:21:27:13 +0200

please suggest pointers.
