title: How to change the p4 submit description
body: <p>I am new to Perforce. Here's the problem:</p>
  
  <pre><code>$ p4 submit
  Change 9 created with 1 open file(s)
  Submitting change 9.
  Locking 1 files ...
  Submit validation failed -- fix problems then use 'p4 submit -c 9'.
  </code></pre>
  
  <p>The problem is that the description that I entered into the submit form was bad. How do I change it?</p>
  
  <p>I checked the docs for p4 submit, and didn't understand what -i does. Maybe that's what I need.
  I tried:</p>
  
  <pre><code>$ p4 submit -i "Better description" -c 9 filename
  </code></pre>
  
  <p>and got:</p>
  
  <pre><code>Usage: submit [ -i -s -r ] [ -c changelist# ] [file]
  Missing/wrong number of arguments
  </code></pre>
  
  <p>Thanks!</p>
