title: How to cat all files with filename with certain words in unix
body: <p>I have a bunch of file in one directory, what I wanted to do is:</p>
  
  <pre><code>cat a-12-08.json b-12-08_others.json b-12-08-mian.json &gt;&gt; new.json
  </code></pre>
  
  <p>But there are too many files, is there any command I can use to cat all files with "12-08" in their filename?</p>
  
  <p>I found the solution below.</p>
