title: Select lines by condition and count with one line command
body: <p>I need help with analyze nginx logs. Sample of log:</p>
  
  <pre><code>10.10.10.10 - - [21/Mar/2016:00:00:00 +0000] "GET /example?page=&amp;per_page=100&amp;scopes= HTTP/1.1" 200 769 "-" "" "1.1.1.1"
  10.10.10.10 - - [21/Mar/2016:00:00:00 +0000] "GET /example?page=&amp;per_page=500&amp;scopes= HTTP/1.1" 200 769 "-" "" "1.1.1.1"
  11.11.11.11 - - [21/Mar/2016:00:00:00 +0000] "GET /example?page=&amp;per_page=10&amp;scopes= HTTP/1.1" 200 769 "-" "" "1.1.1.1"
  12.12.12.12 - - [21/Mar/2016:00:00:00 +0000] "GET /example?page=&amp;per_page=500&amp;scopes= HTTP/1.1" 200 769 "-" "" "1.1.1.1"
  13.13.13.13 - - [21/Mar/2016:00:00:00 +0000] "GET /example HTTP/1.1" 200 769 "-" "" "1.1.1.1"
  </code></pre>
  
  <p>Is it possible to select with count all uniq ip addresses which contain per_page parameter and this parameter equal or greater than 100?</p>
  
  <p>So, the output can be in any format:</p>
  
  <pre><code>10.10.10.10 - 2 # ip 10.10.10.10 was found twice
  12.12.12.12 - 1
  </code></pre>
  
  <p>Is it possible to get with one command?</p>
