I need to read a log file in this format (from squid proxy) :
1280628767.448 155251 192.168.100.225 TCP_MISS/503 902 GET http://googletb.skype.com/skypelist-en.xml
renee DIRECT/googletb.skype.com text/html
and compile a list to a file of everyone who've gone over their qouta - for example 1GB. In the format above the 902 is the usage in bytes and "renee" is the user in that line.
The log files tend to a bit weighty - 500mb+ so there are quite a few lines to work through.
