title: Why can I not use an exclamation mark in bash' echo, not even when it is escaped?
body: <p>My question is simple:</p>
  
  <pre><code>$ echo "Hello!"
  sh: !": event not found
  </code></pre>
  
  <p>What is <code>!</code> in this case? I then tried <code>echo "Match\!"</code>, but that resolves to <code>Match\!</code>. How do I have to write the statement?</p>
