title: Two ways of entering a directory by inode number?
body: <p>If I want to enter a directory by its inode number, why </p>
  
  <pre><code>cd $(find . -inum $inode_num) 
  </code></pre>
  
  <p>works, but the following command does not work:</p>
  
  <pre><code>find . -inum $inode_num -exec cd {} \;
  </code></pre>
  
  <p>what's the difference between these two, and why is the 2nd one wrong?</p>
