title: Copy files from one folder to another folder with filters
body: <p>I have these files in my source folder</p>
  <pre><code>source_path/date=20191230/somefile.txt
  source_path/date=20191231/somefile.txt
  source_path/date=20200101/somefile.txt
  source_path/date=20200102/somefile.txt
  </code></pre>
  <p>If I do the bellow command all files will be copied to my dest_path folder</p>
  <pre><code>cp --recursive source_path/ dest_path/
  </code></pre>
  <p>I just want to copy all folders where dates are in 2020 or something</p>
  <p>I just need these to files of 2020</p>
  <pre><code>source_path/date=20200101/somefile.txt
  source_path/date=20200102/somefile.txt
  </code></pre>
  <p>How can I add filters with <code>cp</code> command</p>
