title: How can I, using Perl, filter out IP addresses from a log file or any other file?
body: <p>I am trying to find out how I can use Perl to scan thru a specific file and find all the IP addresses and block them so that I can convert the numbers in the IP address to x's. For example: 194.66.82.11 and after the code runs it is formatted like <code>xxx.xx.xx.11</code> instead of just removing it completely. This is in unix. </p>
