title: LInux sort/uniq apache log
body: <p>I have  small file (100) lines of web request(apache std format) there are multiple request from clients. I want to ONLY have a list of request(lines) in my file that comes from a UNIQUE IP and is the latest entry</p>
  
  <p>I have so far
  /home/$: cat  all.txt  | awk '{ print $1}' | sort -u  | "{print the whole line ??}"</p>
  
  <p>The above gives me the IP's(bout 30 which is right) now i need to have the rest of the line(request) as well.</p>
