title: How to sort files into folders by filetype on bash (with 'file' command)?
body: <p>I have  thousands of files without extensions after recovery (mostly pictures). I need to sort them into separate folders by filetype (folders must be created during sort process). I can determine filetype in linux using "file" command. Does somebody have bash script for it?</p>
  
  <p>For example: Initial dir contains files: 001, 002, 003, 004. After sorting should be 3 dirs:
  'jpeg' contain 001.jpg, 003.jpg; 'tiff' contain 002.tiff and 'others' contain 004.</p>
