How to delete .svn folder recursively on Linux or mac?

I found the way to delete all .svn folder from my project folder in Linux.
To delete all .svn folder in Linux just follow the steps below:-

• Start Terminal
• change your current directory to your project folder (ex: /var/www/html/PROJECTNAME)
• type [ check if the file list is proper to be sure :) ]
  find ./ -name ".svn"
• type
  find ./ -name ".svn" | xargs rm -Rf
  and enter.

calculate long ip from Ip address - IP number from IP address - ip2number

Today, i came across to compare IP addresses and needed to have it stored in the long int as well. its also called IP number

Reason for storing values in long int  is that it would help to get the ip details like contry and location within its range.

Any IP address is divided into 4 parts. generally each parts has different weightage.

To calculate IP number for any IP address:

IP Number = 16777216 * A + 65536 * B + 256 * C + D

This way we can also get range of IP address.

so if we have IP address say 74.125.236.80 than 

IP Number = 16777216 * 74 + 65536 * 125 + 256 * 236 + 80 =  132406480

I have made a function to calcualte above IP number in PHP, hope its helpful

 Function To get  IP Number from IP Address to in PHP

function ip2numer($ipaddress=''){

      if ($ipaddress == "") {
         return 0;
     } else {
         $ips = split ("\.", "$ipaddress");
          return ($ips[3] + $ips[2] * 256 + $ips[1] * 65536 + $ips[0] *16777216);

     }
