title: How to increase the size of the scrollback buffer in GNU screen
body: <p>How do I increase the number of lines that I can view in <code>screen</code>?</p>
  
  <p>I want to view the lines from the point when I ran <code>screen -S &lt;screen_name&gt;</code> to the current operation. For example, how would I increase the buffer length to around 50000 lines?</p>
  
  <p>I have already tried <code>^a :scrollback &lt;number&gt;</code> but it does not increases the lines I can reach in my current terminal.</p>
