title: why this command does not work: cd `echo -n "~"`
body: <p>Running the command</p>
  
  <pre><code>cd \`echo -n "~"\`
  </code></pre>
  
  <p>I get the following error:</p>
  
  <pre><code>bash: cd: ~: No such file or directory
  </code></pre>
  
  <p>What's the problem if <code>'cd ~'</code> works fine?</p>
