title: Permission denied for a "drw-r--r--" directory
body: <p>I have a log/ directory with read permission for all : <code>drw-r--r--</code></p>
  <pre><code>paul@ns387656:/var$ ls -l
  ...
  drw-r--r--  9 root     root  4096 May 22 14:49 log
  ...
  </code></pre>
  <p>But when I want to access it with the cd command I have a &quot;Permission denied&quot;</p>
  <pre><code>paul@ns387656:/var$ cd log
  -sh: cd: log: Permission denied
  </code></pre>
  <p>And I don't know why...</p>
  <p>Ideas ?</p>
