title: list files from directory between given hours using linux command
body: <p>There are few errors which we need to mitigate which can be done only when I am able to find the list of files which got created between 2 hours.</p>
  
  <p>My file naming pattern is</p>
  
  <pre><code>App_ErrorFile1401_01_11_YYYYMMDDHHMMSS_1234_123456.csv.gz
  </code></pre>
  
  <p>I need to find files which are between 9AM-11AM of yesterday. Having found the list of files I will then FTP those files to a given server IP.</p>
  
  <p>FTP part is something which we can do easily but I am not able to find any pattern using which I can search only 2 hours files and select them for FTP. I dont have much idea of grep with regex pattern and after going through net for more than an hour I am yet to figure out how to build my statement. 
  I can use find/grep. I am on RHEL.</p>
  
  <p>Help would be greatly appreciated.</p>
