title: chmod a freshly mounted external drive to set up writing access
body: <p>I have mounted a external drive at:</p>
  
  <pre><code># mkdir /mnt/external
  </code></pre>
  
  <p>and subsequently:</p>
  
  <pre><code>mkdir -p /mnt/external
  mount /dev/sdb1 /mnt/external
  </code></pre>
  
  <p>Now only the root-user has access to write to these folders.</p>
  
  <pre><code>linux-wyee:/home/martin # dir /mnt
  drwxr-xr-x 2 root root 4096 13. Dez 22:01 external
  </code></pre>
  
  <p>How to change this - how to change that all can write to the external drive. I need to change the permissions within the terminal.</p>
  
  <pre><code>chmod 777 /dev/sdb1 /mnt/external or something alike -
  </code></pre>
