title: How to use tr command in linux to encrypt?
body: <p>I'm trying to figure out how to make the tr command encrypt characters from the space to the tilde (ASCII code 32-126). For example, if I enter a space in the command line, I want to see an exclamation point as my output since it adds one to the ASCII code. Any help would be much appreciated. I tried using</p>
  
  <pre><code>tr ' '-~ 32-126
  </code></pre>
  
  <p>but it was giving me an error.</p>
