title: why I cannot cd into /var/lib/mysql
body: <p>The structure is the following</p>
  
  <pre><code>ravas@ravas-desk-lmde /var/lib $ pwd
  /var/lib
  ravas@ravas-desk-lmde /var/lib $ ls -l | grep mysql
  drwx------ 13 mysql   mysql   4096 Feb 10 22:32 mysql
  </code></pre>
  
  <p>When I try to get into  /var/lib/mysql, I don't have rights</p>
  
  <pre><code>ravas@ravas-desk-lmde /var/lib $ cd mysql/
  bash: cd: mysql/: Permission denied
  </code></pre>
  
  <p>though I belong to the mysql group</p>
  
  <pre><code>ravas@ravas-desk-lmde /var/lib $ groups ravas 
  ravas : ravas adm dialout cdrom floppy sudo audio dip video plugdev lpadmin sambashare mysql
  </code></pre>
  
  <p>What's the problem here?</p>
