IST334: Perl project #4.

Perl project #4

Write a perl script named log_analyzer.pl that does the following:

takes command line arguments as names of files
opens up these files and read their contents (example of the files are here [small] and here [big])
reads every line from these standard APache log files and from each line extracts two pieces of information: (a) the IP address the request came from and (b) the root directory this requests addressed to. For example, in the following line:
```
66.196.72.16 - - [03/Jan/2004:03:59:00 -0500] "GET /ist366/l09.html HTTP/1.0" 200 8515
```
the IP is 66.196.72.16 and the root directory is ist366
saves this information into a hash. Each element of the hash is to be an array of requested directories indexed by IP. In other words, if I want to find out all directories a particular IP address was interested in I need to go to $info{$IP} and I'll get an array containing all main directories.
When you read the complete file and created your hash, you need to sort your hash by the number of directories saved in these arrays (from biggest to smallest) and print the first 15 of them.
