title: unix list files with a full stop in name
body: <p>I have 4 files: the naming convention is as follows:</p>
  
  <pre><code>hello.account.sub1.001  
  hello.account.sub2.001  
  hello.account.sub3.001  
  hello.account.sub4.001 
  </code></pre>
  
  <p>If I use <code>ls -l hello.account*001</code> to search files, no problem exists.</p>
  
  <p>However, problem exists when using <code>ls -l hello.account.*.001</code></p>
  
  <p>The system complains that <code>No such file or directory</code></p>
  
  <p>I assume the system considers hello.account.*.001 is a single file.</p>
  
  <p>This interests me so I ask: how can you search the file if a full stop is specified as searching criteria?</p>
  
  <p>Many Thanks</p>
