title: Why in nautilus you can access directories without execution privileges, and in terminal you can't?
body: <p>When I remove execution privileges (and just leave it with r) from a directory using</p>
  
  <pre><code>chmod 400 sampledir
  </code></pre>
  
  <p>and try to acces with</p>
  
  <pre><code>cd sampledir
  </code></pre>
  
  <p>it says permission denied, but if I use nautilus to open it, i can open it and see its contents, Why is that? I read in some place that i terminal you have to execute the directory and the directory will lists its contents, but I think when you use cd, cd is the program and the directory name would be the parametter. That is just an hipothesis becouse i've been reading on google and i cannot understand yet. Thanks a lot for any help.</p>
