title: How to find file names matching a pattern and copying those in unix?
body: <p>I want to find list of files starting with <code>All_Responses_11367</code> and copy those files to another directory. For example  for each day I have 40 files and need to copy for last 80 days files:</p>
  
  <pre><code>All_Responses_11367_8_20_2013.txt
  All_Responses_11368_8_20_2013.txt
  All_Responses_11369_8_20_2013.txt
  All_Responses_11367_8_21_2013.txt
  All_Responses_11368_8_21_2013.txt
  All_Responses_11369_8_21_2013.txt
  All_Responses_11367_8_22_2013.txt
  All_Responses_11368_8_22_2013.txt
  All_Responses_11369_8_22_2013.txt
  </code></pre>
  
  <p>I would like to copy one same files for all dates at a time.</p>
  
  <pre><code>All_Responses_11367_8_20_2013.txt
  All_Responses_11367_8_21_2013.txt
  All_Responses_11367_8_22_2013.txt
  </code></pre>
  
  <p>I want only last 77 date files by file name, which consists of a date.I want those last 77 days files by file name and not the file generated date. How can I achieve this?</p>
